There are lots of ways to process acorns. These amazing old films show traditional processing in enough detail for a person to really learn something. Processing of the California buckeye is much less common, but this video shows how it is done. The buckeye nuts are poisonous raw, but they are not hard to process and it shouldn't be overly intimidating. It's also just really great to watch these ladies at work with their deft hands, and listen to the singing, which is, for lack of a better description, very grounding. Thanks to the wonders of the information age, these once very hard to get films are now available to see. Check 'em out!
