Everyone has their own method of processing acorns to make them edible. However the method used is usually a variation of each other. Here is my preferred way to process acorns.
- Pour boiling water onto whole shelled acorns and allow to soak for a few hours, then strain off the water (this removes the tannins). Repeat throughout the day. I normally do 3 or 4 changes of water.
- Do as above for 4-5 days. The coloured water will get clearer the more times you do it.
- Then on the last day put acorns in a pan of water, bring up to boil, then simmer for 10-20 minutes. Take off heat and allow to cool. Then strain.
- Either use immediately or freeze.
