I tried the pumpkin muffin recipe using 1/4 cup rice bran instead of gluten free bake mix.

ewww.

Definitely not the right answer. My package was sealed, but may have been rancid, or it might just be the way that smells. I ignored that and made muffins anyway, but they did not turn out well. Just as mushy as when made with 100% almond flour and the flavor was a little odd, and most importantly, it makes my mouth and lips that tingly-numb feeling which usually means bad things.

Back to the drawing board.
