Process acorns into edible flour
Acorns are a high-calorie staple once the bitter tannins are leached out.
Insteading — Eating Acorns: Forage, Store & Cook
Step-by-step
Collect ripe acorns and discard any with holes, mold, or dark stains.
Shell them by cracking with a rock or hammer, then remove the papery skins.
Grind the nutmeats into coarse meal using a mortar and pestle, two stones, or a blender at home.
Leach the tannins by placing the meal in a cloth bag and running cold water through it until the water no longer tastes bitter.
Spread the meal to dry, then use as flour for porridge, bread, or pancakes.
Warning: Unleached acorns are high in tannins and will cause nausea. Taste-test the water runoff — if it's bitter, keep leaching.
