Almond Meal/Flour - Bob's Red Mill. If you can find almonds on sale for $5/pound and make your own flour, you save money, but not time. And, caution, sometimes almonds will turn to almond butter, not flour. See recipes about making almonds into flour.
I love Bob's Red Mill products but several articles (not leading to this link) have reported that Coconut flour is high in fiber and can cause severe bloating for those who have Celiac disease, use it sparingly.
