Posha vs. Thermomix: Kitchen Robots Face Off on Thanksgiving Sides
The holiday season, with its relentless culinary demands, can often leave even the most enthusiastic home chefs utterly exhausted before the main event. For one reviewer, the pre-Thanksgiving testing marathon had already involved four rounds of mashed potatoes, three batches of mac and cheese, and no less than three turkeys – with more awaiting their fate in the fridge. This intense preparation, aimed at testing smart probes for outdoor turkey smoking and crafting elaborate seven-course holiday meal kits for loved ones, had pushed the limits of kitchen endurance. It was in this state of culinary fatigue that the prospect of outsourcing some of the cooking to advanced robotic chefs became not just appealing, but a necessity. The mission: to pit two distinct robo-chef devices, the venerable Thermomix TM7 and the innovative Posha kitchen robot, against each other in a Thanksgiving side dish showdown. Both promised to streamline meal planning and automate much of the cooking process, a vision that, at that moment, sounded like pure liberation.
The Thermomix, with its impressive lineage tracing back to a German device launched in 1968, embodies a long evolution in smart kitchen technology. In an era when the most famous robot chef was the cartoon character Rosie from The Jetsons, the original Thermomix was a groundbreaking blender with an integrated heater. Over nearly six decades, this pioneering appliance has transformed into a culinary powerhouse, gaining multi-tier steaming capabilities, baking and proofing functions, a vibrant touchscreen interface, an expansive recipe application, and a suite of sophisticated smart features. Its global popularity has surged across continents, from the sun-drenched kitchens of Italy and Portugal to the bustling homes of Australia. The previous iteration, the Thermomix TM6, earned high praise from WIRED reviewer Joe Ray, who hailed it as the "smartest of the smart kitchen." The latest model, the seventh-generation TM7, released in August, commands a retail price of $1,699. With its striking design resembling a futuristic trophy topped with a computer screen, the TM7 aims to be the ultimate kitchen appliance, capable of replacing almost every other gadget and even ordering groceries via Instacart.
Entering the robo-chef arena as a relative newcomer is Posha, a device born from a Silicon Valley-via-Bangalore startup, conceptualized to deliver truly autonomous one-pot cooking. Launched in January at a price of $1,750, the Posha kitchen robot quickly sold out its initial batches, a testament to its intriguing promise. The device boasts a distinctive robot stirring arm and an integrated camera that intelligently monitors food for optimal moisture and browning levels. The core appeal lies in its hands-free operation: once the user preps and portions ingredients into designated bins, a simple press of a button initiates a fully automated cooking sequence. Posha takes over, adding ingredients precisely when needed, seasoning and stirring with robotic precision, and incorporating water and oil as required, all without further human intervention.
To truly gauge their capabilities, both the Posha and Thermomix were tasked with preparing a diverse spread of Thanksgiving side dishes. The menu included classic candied yams, creamy mashed potatoes, comforting mac and cheese, crisp brussels sprouts, and a more adventurous "wild card" entry – a dish chosen with a specific family member, Aunt Katherine, in mind, reflecting a desire for something unique yet comforting. The ultimate goal was a comprehensive assessment of the overall cooking experience each robot offered, culminating in a definitive robo-chef face-off.
Cooking Experience With Thermomix
The Thermomix, benefiting from nearly 60 years of iterative development, excels in its core functionality. It remains, at heart, an exceptionally powerful blender with heating capabilities, capable of producing silky pestos or perfectly smooth mashed potatoes with astonishing speed and ease. The sheer raw power of its blending and cooking mechanism elicits genuine awe. Beyond its foundational strengths, however, the Thermomix has evolved into a multi-functional marvel, designed to consolidate and replace a multitude of kitchen appliances.
This sophisticated device goes far beyond simple blending. It generates shopping lists, accurately weighs ingredients directly within its bowl, and features a multi-tiered "Varoma" steaming tray for simultaneous cooking. It can blend, mix, roast, and even proof bread dough, all guided by its Wi-Fi-enabled touchscreen computer. Imagine preparing a complex sauce, a rice bowl, and steam-grilled salmon all at once – the TM7 makes it possible. Claiming to replace over 20 devices, it even integrates with meal kit subscriptions by transferring shopping lists directly to Instacart for convenient grocery delivery. Its extensive "Cookidoo" app, a treasure trove of culinary knowledge, offers over 100,000 meticulously tested recipes, ensuring a new dish for every meal for 91 years.
Despite its advanced features, the Thermomix isn’t a fully autonomous chef in the traditional sense. Instead, it functions as a highly intelligent culinary assistant that dictates instructions to the user. One might consider the Thermomix the executive chef, and the human user the dedicated prep cook. The onus remains on the user to chop ingredients and add them at precise moments, guided by the on-screen prompts and the device’s integrated weighing scale. Occasionally, the Thermomix might even instruct the user to transfer ingredients to an external oven for further cooking. Nevertheless, its beautifully insulated cooking and baking bowl, coupled with its immense power and the sophistication embedded in its recipes, make for an impressive cooking experience. Indeed, one of the reviewer’s most memorable meals of the year – a delightful walnut squash with roasted vegetables and arugula pesto – was crafted with the Thermomix.
Cooking Experience With the Posha
Posha’s compelling tagline, "See dinner cook itself," largely encapsulates its core promise. To initiate cooking, the user must ensure the device’s reservoirs are adequately filled with cooking oil and water, and that prepped and chopped ingredients are meticulously placed into four designated plastic bins on the machine’s left side. Additionally, proprietary "spice grenades" containing various seasonings must be loaded into a rotating tray, reminiscent of a 1990s CD changer. Once these preliminary steps are complete, however, the Posha truly takes over, operating with remarkable autonomy.
This innovative device is fundamentally a one-pot cooker, featuring a custom nonstick pan that accommodates a Robotix-style robotic arm. This arm, equipped with one of three interchangeable spatula configurations, meticulously stirs and flips food throughout the cooking process. An overhead camera vigilantly monitors the dish, assessing moisture levels and browning, guiding the device through a series of steps: browning ingredients, stirring, adding water, and reducing liquids.
While each recipe typically takes longer than one might initially expect – Posha is, by design, a patient device – the beauty lies in the complete lack of user intervention during the cooking cycle. There’s no need to remain in the kitchen; the cooking can be monitored remotely via a smartphone app, which periodically sends photographic updates of the food’s progress. The name "Posha" itself is derived from the Hindi and Sanskrit word for nutrition, a reflection of its origins and the initial strong emphasis on Indian cuisine within its recipe library. The reviewer noted enjoying the process of learning Indian cooking through Posha, observing its unique approach even to non-Indian dishes, such as chicken fajitas, which it prepared using classically South Asian techniques like blooming spices in oil.
Currently, Posha offers around 1,000 recipes, each developed by a dedicated team of four full-time chefs who actively respond to user recipe requests. This user-driven expansion ensures the repertoire evolves based on its community’s preferences. Posha’s customer service proved remarkably responsive; rating a dish two stars on the device immediately prompted an email inquiry about the dissatisfaction. However, as with any nascent technology, occasional glitches arise. The robot arm might sometimes disconnect, halting the process, or ingredient bins might fail to register. The common troubleshooting solution, often humorously reminiscent of IT support, is to "turn it off and on again." Despite these minor hiccups, Posha’s core functionality allows users to press start and walk away, receiving a phone notification when dinner is ready – a feature so liberating that the company’s website comically depicts a woman "falling asleep with a glass of wine next to the thing."
For those keen on the granular details of how these kitchen titans performed, here’s a breakdown of their performance across five holiday dishes:
Test 1: Candied Yams
Candied yams, a beloved holiday staple, are traditionally slow-cooked in a skillet or baked in a casserole, generously coated in a sweet, buttery glaze. (It’s worth noting these are, botanically speaking, sweet potatoes, but the holiday spirit overlooks such distinctions.) For both robots, the user served as the essential prep chef and dishwasher, peeling and cutting several pounds of sweet potatoes before the cooking began.
The Posha proved remarkably well-suited for candied taters. After the yams were prepped and the requisite butter, brown sugar, and nutmeg were loaded into the bins, the device embarked on a patient skillet-cooking process. Over approximately half an hour, it gently browned the yams to a lovely, tender consistency. Posha’s true strength lies in these slow skillet cook-downs, achieving a rich and desirable Maillard reaction over low heat with a patience that often surpasses human cooks.
The Thermomix, while adept at creating a luscious and sticky butter sauce through its powerful mixing and heating capabilities, delegated the actual yam cooking to an external oven, requiring sheet trays. The reviewer noted a preference for skillet-cooked yams over oven-baked versions, and this held true here. Despite simple prep, the necessity of using two devices and preparing sheet pans extended the overall time and effort significantly.
Ultimately, while both dishes were palatable, the Thermomix’s version lacked the textural depth and caramelized splendor of Posha’s roasty, candied rendition.
Candied Yam Victory: Posha
Test 2: Brussels Sprouts
Neither robot’s recipe app offered the elaborate, gourmet brussels sprouts often found on modern Thanksgiving tables – dishes replete with walnuts, maple glaze, parmesan, or chili. Both Posha and Thermomix opted for a simpler approach: salt, pepper, and garlic for Posha; salt, pepper, and lemon for Thermomix. However, their cooking methods differed. Posha, leveraging its pan-cooking design, gently charred the sprouts over low heat. The Thermomix, conversely, called for a brief steam in its internal steam basket, followed by a roast in its main bowl to achieve browning.
In the final assessment, Posha’s sprouts, despite the machine’s declaration of completion, required additional cooking time and ultimately fell short of the Thermomix’s output. The TM7 produced moist, flavorful, and nearly perfect brussels sprouts. A minor drawback for the Thermomix was the more demanding cleanup, necessitating a water-vinegar pre-clean cycle and considerable scrubbing to remove stubborn brown bits from its stainless steel interior.
Brussels Victory: Thermomix
Test 3: Mac and Cheese
While both devices had performed admirably so far, the Thermomix encountered a significant hurdle with mac and cheese. Although its "Cookidoo" app features numerous promising mac and cheese recipes involving oven-baked casseroles, the reviewer chose a recipe designed for cooking entirely within the Thermomix bowl.
This choice proved disastrous. The recipe’s water-to-noodle proportions seemed off, and crucially, there was no step for draining the pasta. The final instruction – to dump a large quantity of cheese into the bowl all at once and then stir – defied culinary intuition. Adhering to the recipe, a massive glob of cheese inevitably formed. The Thermomix bowl, unsuitable for effectively mixing the congealed cheese, forced the reviewer to transfer the entire contents to a stovetop pan for proper emulsification, by which point the noodles were overcooked and mushy.
Posha, however, handled pasta with surprising finesse. Its ability to accurately measure water for a given weight of noodles yielded consistently good results. While a spaghetti marinara recipe didn’t quite hit the mark on sauce flavor (too much dry herb), the noodles themselves were perfectly al dente. The mac and cheese followed suit, delivering well-textured noodles after a prolonged, low-heat cook-down, and a creamy, satisfying cheese sauce. It was also one of the easiest recipes to prepare on Posha, rivaling the simplicity of instant boxed versions.
Mac and Cheese Victory: Posha
Test 4: Mashed Potatoes
This round saw Posha stumble, producing a result that was, at best, peculiar. As a dedicated one-pot cooker, Posha attempts to execute every step autonomously, including water management. This meant it had to add sufficient water to cook the potatoes, then patiently cook down all that water before incorporating butter and milk for mashing. This protracted process, spanning at least an hour, subjected the potatoes to an intense and prolonged cooking.
By the time the potatoes were boiled, reduced, enriched with milk and butter, further reduced, and then "mashed" with a silicone stirrer, their original texture had been utterly obliterated. The resulting creamy, gluey substance resembled the interior of a twice-baked potato, heavily laden with fat, akin to a fried potato puree. While not inherently bad-tasting, it was an unprecedented level of potato subjugation.
The Thermomix, conversely, was seemingly engineered for mashed potatoes. The process was astonishingly fast, effortless, and resulted in lump-free, airy, and exquisitely creamy mashed potatoes. The entire experience was the Platonic ideal of mashed potato preparation. Even skipping the recommended peeling step didn’t diminish the magnificent outcome.
Mashed Potato Victory: Thermomix
Test 5: Wild Card
Beyond the standard holiday fare, a "wild card" dish was selected from each device’s unique recipe library, based purely on aesthetic appeal and an autumnal, root-vegetable theme.
From Posha, leaning into its strength in Indian cuisine while keeping it mild for a family gathering, the choice was carrot poriyal. This gentle Tamil Nadu dish features carrots, toasted coconut, and a Madras spice mix incorporating mustard seeds and savory herbs, along with a subtle hint of green chili, no spicier than black pepper.
This dish proved to be a genuine delight, both in its straightforward preparation and its exquisite outcome. The coconut was perfectly toasted, and the carrots were lightly browned and cooked through, infused with layers of aromatic spice and wilted greens. It was a dish the reviewer would happily serve to family, initially believing it would secure the wild card victory. Indeed, every Indian dish prepared with Posha consistently surpassed expectations, often outperforming local Punjabi restaurants, though sourcing specific ingredients like curry leaves could be a challenge depending on location.
Then came the Thermomix’s offering: a walnut squash with roasted vegetables and arugula pesto. This dish, a quintessential example of "New Englandy WASP Thanksgiving," struck the reviewer as almost comically Martha Stewart-esque in its refined vision of luxury.
The pesto preparation was incredibly swift, almost surreal. While the Thermomix vibrated and clattered like a bag of rocks when blending nuts, the pesto itself was near-instantaneous, yielding a beautifully dense and flavorful concoction (the recipe was vegan, but real parmesan was substituted). However, the squash preparation was considerably more laborious, involving the splitting, peeling, and cubing of multiple varieties of squash or sweet potato, followed by baking them on sheet pans in an external oven.
Yet, when the final dish was assembled, the arduous prep was instantly forgotten, much like how mothers are said to forget the pain of childbirth upon holding their newborn. The dish was simply phenomenal. Its rich texture, vibrant contrasts, generous use of fat, earthy depth, and bright lemony notes created a truly exceptional culinary experience. A colleague, a former high-end line chef, tasted it and paused in admiration, declaring, "We would have served this at the restaurant." This was, without a doubt, the dish that now had to be brought to the family Thanksgiving.
Wild Card Victory: Thermomix
Which Is Better, Posha or Thermomix?
Based purely on the culinary outcomes, the Thermomix emerges as the winner, securing victories in three out of five dishes. Its long-established presence and extensive library of tens of thousands of recipes, meticulously developed over generations and across diverse cultures, give it a significant edge on the culinary front. Posha, as a newer entrant, has considerable ground to cover in terms of recipe breadth and refinement.
However, Posha undeniably offers a more seamless user experience. Its cook times, on average, were slightly shorter, largely because the Thermomix frequently relies on extended oven bakes for many recipes. Posha’s average difficulty rating for recipes hovered at a mere two out of ten, reflecting its ambitious design for automated home cooking. It’s a device that performed far better than one might expect from such new technology, offering a more realistic glimpse into an automated kitchen future than the fanciful human-sized robots often envisioned.
Yet, Posha still carries the inherent risks of new technology. It presents numerous potential points of failure and occasional glitches, a "nest of firmware updates" that signifies a work in progress. Pre-orders are backed up for months, requiring a leap of faith from consumers willing to pay a nominal fee to "hold" their order. While Thermomix is a tried-and-tested stalwart, Posha’s long-term reliability and longevity remain an unknown. Furthermore, the sheer counter space required for both similarly priced devices is a significant investment.
If a choice had to be made between these two equally priced devices this year, the reviewer would opt for the unwavering, proven reliability of the Thermomix, which offers the added practical benefit of fitting neatly into a cabinet when not in use.
However, the landscape could very well change by next year. Posha, despite its nascent status, already performs better than anticipated. Witnessing the speed and responsiveness of Posha’s customer service, coupled with insights from Posha CEO Raghav Gupta during a device demonstration, provides strong reasons for optimism regarding the company’s and the device’s future. Gupta’s vision for the next generation of Posha, potentially mounted above the stovetop rather than dominating counter space, hints at a thoughtful evolution.
The ultimate victor in the robot wars of the future remains to be seen. But as things stand right now, the reviewer is certainly not betting against Posha.
