Acorns are good for baking because they add texture. And they don’t have gluten in them either which is why I add whole wheat flour when I bake them into bread. When I made acorn cheesecake for Thanksgiving, the acorn meal absorbed the egg whites in the baking process and it came out very nice. You definitely need to add flour to acorns though, if you are making bread or cookies. You don’t need a lot of acorn meal to make a batch of muffins or a loaf of quick bread. One half a cup of leached acorn meal is plenty. Using a smaller amount is a good idea for beginners and be sure to mix the flour and acorns well. The way I use acorns, they are wet so I would add them to the batter after I add any liquids, including eggs.
