Acorn flour from black oak

Oak (Quercus robur)

The oak was very popular with our ancestors. In many ancient cultures, oaks were sacred trees that were often associated with lightning gods. Sacred meaning and medicine used to be very close. This is clear from the fact that the Celtic word druid (priest) is derived from “duir” (oak). Even today, oaks have a lot to contribute to medicine ...

    Oak in the kitchen

    Acorns were an important source of food for humans in earlier times and in times of need. With a lot of ingenuity, flour was extracted from acorns and made into bread, cakes, soups, pudding and coffee. Here are some well-tried recipes ...

    Basic recipe no.1: acorn flour (5 kg acorns make approx. 3.5 kg acorn flour)¹

    1. Dry acorns well (e.g. store on the heater)
    2. Remove the outer shell with a food processor (coarsest cutting blade attachment)
    3. Soak acorns in cold water for 24 hours (2 liters of water are required per 1 kg of acorns, which should be changed twice within 24 hours. This is the only way to adequately remove the tannins contained in the acorn.)
    4. After watering, cook acorns for 15 minutes (this makes them easier to digest)
    5. Drain on a sieve and dry for 24 hours at room temperature
    6. Then grind the dried acorns (also works in a blender)

    The finished flour should be light yellow in color. The smell of the flour is somewhat reminiscent of the wood of oak.

    ¹ The recipe takes up the knowledge of the bachelor thesis mentioned under [2].
