Oak – specifically the acorn – is a great source of food in the fall and early winter time. Like most nuts, acorns contain a good amount of protein and fat which is beneficial in keeping you alive. While White Oak species of acorns can be eaten right after shelling, the remaining oak varieties require processing of the acorns first in order to remove the bitter taste.
The best way to do this is to crush the acorns into a course flour then immerse this flour into water and boil it. Depending on how much water used, it can take only one boiling (at most two) to remove the bitter taste.
