You pull a batch of muffins out of the oven, expecting a tender crumb, but one bite reveals a texture somewhere between a kitchen sponge and actual desert sand. It is the classic coconut flour trap—a high-fiber ingredient that drinks up liquid like a marathon runner in July. Understanding how this specific flour behaves is the difference between a treat you actually want to eat and something that ends up in the compost bin. This guide covers why coconut flour is so picky about moisture and how you can fix the crumbly, dry mess that plagues so many low-carb kitchens.
