This is one smart piece of equipment. It is a very powerful blender that can go from 100 rpm's to 12000 rpm's in fractions of a second. It has the added bonus of a heating element (which heats in intervals of 10 degree Celsius increments strangely starting at 37 degrees Celsius, then 50, 60, 70 and so on up to 100), an integrated scale, a sharp blade that can be switched to a paddle or a mixer attachment. If you go to the Thermomix website you can see all that this machine can do. Some of it I take exception to, such as kneading bread.
But here is a good example of complete functionality: you can scale all of the ingredients of a creme anglaise directly into the blender cup attached to the body of the machine. Switch to blend, and press the desired temperature, which is 80 degrees Celsius, for a set amount of time, let's say three to four minutes. Turn the machine on to speed 5 (speed 10 is reckless) and it will produce a very smooth, napped anglaise.
I have successfully made many excellent ganaches in it, simply by placing all of the ingredients in the cup, setting the time, the temperature and the speed. Always a smooth result.
Most exciting though, is that I was able to produce an outstanding foie gras mousse, fully cooked, in less than 3 minutes. It is in the picture at the beginning of this post. I had baked feuille de brick cylinders. Once the mousse was made, I was able to pipe it into the crisp brick tubes. You could effectively make foe mousse to order, perfectly smooth, like soft butter.
There are two cons to this machine, cost (close to $1700) and it only holds the equivalent of two liters of liquid or up to two kilos of solid matter, so it is not so much for a professional kitchen. Although it holds the perfect amount to fill a 12 inch steel caramel frame of ganache. And it can process two 700 g lobes of foie at one time.
Highly recommended. And here's a catch, you won't find them as readily as you would any old blender. It is usually sold from a real actual human being to another, and very few will sell it as a retail item. What they are looking for, I have heard, is to be able to show you in person how many things the machine can do, since it is not really much to look at. It is excellent for home use I suppose. You could potentially eliminate many appliances you have at home that are collecting dust. Here is one you could quickly recycle: your ice cream machine. How, you might ask, does this machine make sorbet or ice cream? Make your ice cream base or sorbet base, pour it into an ice tray, freeze it, pop the cubes out, put them in your Thermomix on the turbo setting (because this being a German machine it has a turbo setting) and in a few seconds it will grind your rock hard cubes into a smooth frozen dessert. Incredible.
