Welcome Therese de Wolf

I look forward to seeing the results, its a great idea, i never even thought about doing anything like that when i started.
Might take a while for cravings to go, especially favs like cheese. You can make some nut cheeses as a replacement to tie you over. I cant remember the exact recipe, but there are probs some on here for cashew cheese, i think its cashews, lemon juice, spices maybe?
Alternately, checkout goneraw.
www.goneraw.comTheres heaps of recipes on it, am sure you can find a substitute on it. Just make sure you have really raw cashews since your doing 100%, and if its being tested you probs dont want to have any dead foods like shop bought cashews. You can buy really raw cashews on here, ive never tried them but are meant to be good.
Otherwise if you make a raw pasta, or just want the parmasan thing, i use pinenuts and grind them up with a parmesan cheese grater over food, is a good substitute.
