Acorn flour is a gluten-free flour made from ground acorns, the nuts of oak trees. It is traditionally produced by leaching the tannins from the acorns to remove bitterness before drying and grinding them. This flour has historical roots in the cuisines of Native American tribes, Korea, and parts of Europe, where it was a vital survival food.
Acorn flour is a nutrient-dense, low-fat flour that is a good source of complex carbohydrates and dietary fiber. It provides a moderate amount of protein and is notably rich in minerals like potassium and magnesium, with a rough calorie estimate of 120-150 calories per 1/4 cup (30g) serving.
