We’re heading for a time of grocery shortages. It’s wise to learn to use the plants around you. Consider the high-protein humble acorn.
Acorns are typically harvested between September and November, when they fall from the trees and become easily accessible to deer, squirrels, and resourceful humans.
HOW TO COLLECT ACORNS
When gathering acorns, look for brown, fully mature acorns that still have their caps, as those without caps are more susceptible to infestation by worms and other critters.
Green acorns are not yet mature and shouldn’t be used. If you’re willing to wait, consider harvesting acorns this year and storing them in a cool, dry place until next fall, when they’ll be fully dried and easier to work with.
Let’s get into what to do with them once you’ve collected a bag of these nutritious nuts.
HOW TO WASH ACORNS
- Give acorns a quick rinse in cool water. Place them in a pot or bowl and fill it with water, then remove and dispose of any floating acorns, as they have likely gone bad.
- Place the acorns in a colander and run them under the tap for a minute or two to dislodge any loose dirt or hitchhiking bugs.
- Set the colander aside to let the acorns air-dry, or simply dry them by hand with a dish towel.
- Remove the shells and caps from your acorns with a nutcracker (or a hammer, if necessary). Do not eat the raw meat of the acorns yet.
HOW TO LEACH ACORNS
Acorns contain bitter-tasting tannins, so you must prepare, treat and cook the nuts before you eat them. It sounds like a pain but it’s really not that difficult.
- Start two pots of water boiling. Drop the raw, shell-less acorns into one pot and boil until the water is the color of strong tea. Strain the nuts through a colander and drop the strained nuts into the second pot of boiling water. Discard the dark water from the first pot, then refill it and bring the water to a boil again. Repeat the process without interruption (do not let the acorns cool) until the water boils clear. This may take an hour or more, depending on the variety of acorn.
- Alternatively, you can soak the raw acorns in cold water to leach the tannins out. Change the water when it turns a darker color. This process may take several days, depending on how long it takes for all the tannins to leach out of the acorn meat.
To avoid rotting, it’s very important that the acorns dry fully. Spread tannin-free acorns to dry on cookie sheets in a warm place. If it is hot out, lay the cookie sheets in the sun. Or, you could put them in an oven set to “warm.” You can also put the acorns in a dehydrator set on low heat.
EATING ROASTED ACORNS
Making acorn flour isn’t the only way you can enjoy acorns. Here’s how to roast the nuts:
- Preheat your oven to 350 degrees Fahrenheit.
- Pour the acorns into a single layer on an ungreased, rimmed cookie sheet.
- Cook the nuts for about 60 minutes or until they turn a chocolate brown color.
- Remove the acorns from the oven and let them cool. Salt to taste.
HOW TO GRIND ACORNS FOR FLOUR
When partially dry, coarse grind a few acorns at a time in a blender. Spread the ground acorns to dry on cookie sheets, then grind again in a blender. Repeat until you are left with a flour- or cornmeal-like substance.
You can also freeze your fresh acorn meal. Store dried flour in jars in the fridge.
ACORN RECIPE IDEAS
- Mix up cooked acorns with raisins or other dried fruit to make a trail mix.
- Substitute acorns for chestnuts in baking recipes.
- Use acorn flour in bread, cake, pancakes, and more! Try this acorn flour flatbread recipe (similar to tortilla).
- Or, try this acorn flour honey cake, whichtastes a little likegingerbread cake.
- The flour also makes an excellent pasta dough when mixed with regular flour.
- How about adding acorn flour to a pancake recipe for that nutty taste and nutrition?
Acorn Pancakes Recipe
This recipe adapted from Sharon Hendricks. Source: Texas A&M University AgriLife Extension
- One egg
- 1 tsp. salad oil
- 1 tsp. honey or sugar
- ½ cup leached and ground acorns
- ½ cup cornmeal
- ½ cup whole wheat or white flour
- 2 tsp. double action baking powder
- ½ tsp. salt
- ½ cup milk
Break egg into bowl and add all ingredients, beating to create a batter. If batter is too thick, thin with additional milk. Pour batter onto hot, greased griddle and cook slowly until brown. Flip to brown opposite side. Serve with butter and syrup or jam—and enjoy!
Have you ever made your own acorn flour? Let us know how it went in the comments below!
Makes 6-8 piadine, depending on size
- 2 ¼ cups unbleached all-purpose or bread flour
- ¾ cup acorn flour
- 1 1/2 teaspoons salt
- 3 tablespoons olive oil
- A scant cup of water (7/8 cup to be exact)
- Sift the flours and salt together in a large bowl and make a well in the center.
- Add the olive oil and water in the center of the well and swirl to combine with a finger or two. When the dough gets shaggy, start bringing it together with your hands, then knead it on a floured surface for 5-8 minutes. Use a bit more flour if it is too loose.
- Lightly coat with more olive oil, wrap in plastic and set aside for at least an hour. This dough can hold in the fridge for a day.
- Take the dough out of the fridge if you’ve put it in there and let it warm to room temperature. Get a griddle or a well-oiled cast iron pan hot over medium heat.
- Cut the dough into equal parts; I’d suggest between 6-8. Roll them out one at a time with a roller and then your hands – they need not be perfect, as this is a rustic bread. You want them thin, though, about 1/8 inch.
- Lightly oil the griddle and cook the piadine one or two at a time for 2-3 minutes, or until it begins to get nice and brown. Flip and cook for another 1-2 minutes.
- Keep them warm in towels while you make the rest. Serve with some cheese, fresh herbs – green onions are excellent with this – and some high-quality olive oil.
