......I'll keep the commercial Cuis - 20 cup capacity (= 4.73 liters) because some of my "standard" recipes require the greater capacity. (I use it for slicing cucumbers and zucchini for my bread and butter pickles which are sliced extra thin. I could use a mandoline but in the amounts I use it would be very tiring on my arm. )
I love all of these ideas, expecially changing the lid so it doesn't drip over the Thermomix and make a mess on my bench when i take it off. A silicone spatuala is also a must for me, I find the Thermomix spatula is not very good for scraping the sides or getting dregs of the bottom as it does not bend to the bowl.A spout for pouring would also be amazing.
