Acorns are the nuts from an oak tree and have a long history as a food source in America. You can cook acorns by roasting them for about an hour. Once roasted, acorns can be enjoyed on their own or you can grind the nuts into a meal and use it to make breads or hot cereal. Acorns are not difficult to prepare but doing so is time consuming. Acorns have bitter tannins and you must remove the tannins before you can eat the acorns.
Fill a large pot with water and bring the water to a boil.
Add the acorns to the water and boil for two hours.
Change the water when it turns light brown to ensure the tannins are fully removed. The brown colour appears as the tannins are released; the fresher the water, the more tannins will be removed. Change the water three to four times during the two-hour period. Keep an extra tea kettle of water boiling to replenish the boiling water.
Remove the acorns from the pot using a slotted spoon and spread them on a baking tray.
Roast the acorns at 191 degrees Celsius for 50 to 55 minutes.
Take the pan out of the oven and let cool for 10 minutes before eating the acorns. You can enjoy the acorns hot or let them cool and grind them into a powder to use in recipes.
