I had never heard of ThermoMix, so I looked it up. That is some tool! Can you actually mill grain with it?

A pressure cooker is different - the main value, to me, is that it cooks very quickly, makes meat very tender, and keeps in the flavor of foods, especially meats. (I know that last goes against the traditional reputation of pressure cookers, but in our case it has certainly been so.)
apparently you can mill your grains before baking with the unit, friends and relatives have been oooh-ing over the thermomix for a while. Ahh,now I see... what you’re discussing is a pressure cooker... I have an old fashioned one that goes on the stove. It’s the best thing for cooking/stewing cheaper cuts of beef that come out mouth-watering and tender.
