So I use a lot of almond flour, but that's safe for me. My wife is more the baker, but its usually a mix of bobs and almond flour, and for each recipe its a bit different.
Also been trying out watermelon seed flour. Its sweeter, so it seems good for cookies and the like. Its higher in protein, but also fat content. It also is a bit more runny than almond flour batter, but works nicely for things like waffles and pancakes I think. Still nailing down getting it fluffy the right way, again mixing in some general purpose bobs flour to find the right mix.
Then you've got your brown and white rice flours. The white rice flour is a bit more neutral in flavor, and like the watermelon flour good for stuff like pancakes. For more of a breading kind of flour, or at least more thickening, the brown rice works.
Not exactly recipes, just some stuff I'm mixing in to try, but I hope this at least helps!
