I don't mind experimenting a bit to find a recipe that works, but I could use some ideas on where to start - what sort of ingredients might bind the rye so that it doesn't crumble as a thin pizza base and maintains a low glycemic index for my diabetic wife.
[Psyllium husk]Psyllium husk is the general go-to binder for low-carb bread, but I have not seen a recipe using it in rye pizza dough. Another alternative is to give up on substituting bread and use the same toppings with something else. A frittata does not add much extra work and works well with standard pizza toppings.
