Place the tomatoes into the Thermomix bowl and chop 10 sec/speed 8.
Strain through the nut milk bag into another jug. (Discard solids, or see notes below.)
Return the liquid to the Thermomix bowl and add the salt and sugar to taste. Cook 20 min/80°C/speed 4/MC off. (Use the spatter guard or simmering basket on the lid to prevent a mess.)
Chill juice and use in any recipe as suggested.
NOTE: we spread our solids onto a silpat mat and dehydrated them for 3 hours at 80°C. We will use them in salads. Another use for them is in the Umami Paste recipe. You can also add the dehydrated leftovers to our Chicken Stock Powder recipe or even add them to good ole Veggie Stock paste from Thermomix themselves.
