An important note before I launch into this post .... we do own a Thermomix but are in no way affiliated with or sell Thermomix products, nor are we getting any kickbacks for this post.
We have had a Thermomix for some time now and to be perfectly frank, it has taken quite some time to get the best out of our Thermomix. It's an entirely different way of cooking and thus can be challenging to intuitive cooks initially. (BTW, the corned beef steaming in the Thermomix as we speak smells just wonderful!)
We feed lots of people each week and the Thermomix gets used at least once a day (sometimes it is working for many hours a day when we do batch cooking). This is an important distinction in that we cook 95% of our food from scratch and food prep is a big component of that. For this reason our Thermie works hard and certainly pulls its weight.
We ended out buying an additional pot for our Thermie so we could easily swap pots and continue on with the next recipe. This works especially well when there is more than one person working in the kitchen at a time creating separate courses or meals. The extra cost for the additional pot was worthwhile for efficiencies sake (your mileage may differ).
A new Thermomix is around the $2200 mark at time of writing and can reasonably expect to last at least a decade. That's a yearly cost in today's money of $220/annum. Do your sums to see if this is really worth it for your particular circumstances.
A Thermomix will efficiently chop, beat, blend, whip, weigh, mill, knead, mince, steam, cook, stir, boil and confit. Additionally, there is an online community which is astoundingly useful when learning and experimenting with a Thermomix with literally 100s of thousands of recipes available and many expert users happy to share their knowledge freely.
- Does the job of many separate appliances
- Extremely space efficient
- Robust and engineered to a high standard for longevity
- Actively supports whole/fresh food regimes
- Eliminates waste
- Easy to cook for nutrition (e.g. fresh baby food from scratch)
- Very fast food prepping
- Saves significant amounts of time
- Single pot clean up
- Power efficient compared to using oven/cooker and separate appliances
- Does not caramelise or brown like traditional cooking
- Is an entirely different way to cook (learning curve anxiety)
- Removes the cook from essential techniques of cooking (a boon for bad cooks but a pain for excellent cooks)
- Does not cook several dishes at once - cooks linearly.
- Expensive upfront costs
- Veracity of online recipes can be questionable (AKA Pinterest nonsense recipes)
- Some recipes are just better done traditionally (e.g. scrambled eggs IMHO)
- It can't cook everything (e.g. a roast with crackling or ice cream etc)
