I don’t know if anyone has mentioned this before but I use Dark Rye Ryvia in place of Scan Bran in recipes, seems to work perfectly ok and is a lot cheaper.
dark rye ryvita are 1 half each do you use the same amount so instead of 5 scan bran 5 ryvita ... that would make the base for a cake 7 half syns before adding any choc options or other ingredients
