Coconut
Coconut flour, a gluten and grain-free flour, is ground from the fibers left behind from the coconut meat after it has been extracted of its oils for making coconut oil. Coconut flour is very absorbent. You’ll notice after letting your batter sit for even less than a minute that the batter will tighten because it absorbs a lot of the liquid. Most recipes including coconut flour will have extra moisture either from eggs or fat.
