• On the Farm: Recipe for Acorn Cookies

    Fresh Acorn Cookies

    Now I am going to share with you a couple of recipes that you can make using fresh acorns.  To learn more about acorns check out On the Farm: Acorns Are For Squirrels and how process fresh acorns so you can use it in recipes here is a post On the Farm: How to Prep Acorns for Cooking.

    Once you are ready to use your fresh acorn meal or flour here is one of the recipes you can try:

    Acorn Cookies:

    • 2 cups All Purpose Flour
    • 1 teaspoon Salt
    • 1 teaspoon Baking Powder
    • 1 cup Brown Sugar
    • 1/2 cup Shortening
    • 1 large Egg
    • 1 cup Acorn Flour
    • 1 teaspoon Vanilla Extract

    Preheat the oven to 350 degrees.  In a separate bowl mix the flour, baking powder, and salt.  In a larger bowl cream the shortening, egg, and sugar together.  Gradually add the flour mixture to the cream mixture.  Blend in the acorn flour.  Add the vanilla extract until blended well.  Take a medium size ice cream scoop and place onto a greased cookie sheet.   Use a fork to slightly flatten the balls.   Bake for 10 to 12 minutes.

    The cookies are not as moist as a Chocolate Chip Cookie but not as dry as Shortbread Cookies.  They are a little dryer then I expected but they turned out pretty well.  We shared this recipe with our Community Group and people at Jake’s work.  It was a fun recipe do make and share with others.  I would make sure that those eating do not have a nut allergy.  It provides an interesting conversation started and you are sure to be the only one at the event with Acorn Cookies!  Now if I can just find an acorn cookie cutter.  Stay tuned for some more of our acorn recipes in upcoming posts!

  • On the Farm: How to Prep Acorns for Cooking

    Fun Fall Experiment - Processing our acorns so we can cook with them.

    I recently decided to experiment with cooking acorns and the adventure turned out pretty well.  There are some things I will do differently the next time around but overall the whole experience was educational and enjoyable for the whole family. To learn how I decided to go on this unique venture you can read about what got me started in my post  “On the Farm: Acorns Are For Squirrels”.

    I am always looking for ways to teach my children and since the Fall season is here after a few comments, questions, and some researching about acorns it was decided that our next activity was to go through the complete process of gathering, sorting, opening, processing and cooking with acorns (now that we know that acorns are not just of squirrels).  Here are the Five Steps to gather, sort, crack, and process the acorns in a day instead of doing it the traditional way of putting them in a stream or burying them in mud and waiting weeks before you can eat them.

    Bucket full of acorns

    Step 1 – Gathering Acorns:

    • Each family member took a bucket or bag and headed outside to start collecting acorns.  We found a couple trees that had acorns under them and started filling our buckets. Please see “On the Farm: Acorns Are For Squirrels” to find out which trees to collect acorns from.
    • Inspect each acorn as you pick it up for holes or cracks.  Some good ones will have the caps on others will no longer have the caps attached.  (I discovered later that we were not good at detecting microscopic cracks or holes in the acorns, so later we just gathered the acorns and used the sorting step to eliminate the bad acorns, see below).
    • Fill up your bucket or bag and pour all the acorns into a large sink
    Filling up the sink with acorns and water.
    • Tips to help with gathering (I discovered some ways to make this process easier for the future acorn gatherings):
    • You don’t need to look at each individual acorn, the sorting process is much better at isolating the bad acorns and making sure only the good ones remain.
    • Observe what the wildlife is doing prior to picking up acorns.  For example if the squirrels prefer certain trees then head for those trees first because the acorns will most likely contain less tannins and have less of a problem with bugs.  Trust the animals instinct, they go for the good ones first.

     

    Filling up the sink with water to see which ones will float.

    Step 2 – Sorting Acorns:

    • Put all the acorns in a large sink, plug the sink and run cool water over the acorns.
    • The water level should be several inches above the acorns on the bottom to help with the sorting process.
    • The acorns that are crack, have holes, or that are bad will float to the top of the water.
    • The good acorns will sink and remain on the bottom.
    • Remove all the acorns that are floating and leave the good ones on the bottom.
    • Stir the acorns with your hands (or a paint mixer) to shuffle around the acorns, if any more float to the top of the water remove them.
    Stirring them with the paint mixer to see if there are any more floaters.

    Tips to help with sorting:

    • We used a large utility sink to sort the acorns.
    • Don’t worry about inspecting every acorn (see the Gathering Acorns step above) before putting it into the sink.
    • This sorting step will eliminates 99% or more of the bad acorns in your batch so you can speed up the gathering step by not looking at each individual acorn.
    • You may be surprised at how many acorns are floating
    • You may need to go back out in the yard and pick up some more acorns.
    • In some batches we had as many as half of the acorns floating to the top.
    • Throw away any floating ones because they are not good so you don’t want to waste your time cracking them if you cannot use them.
    • We used the paint mixer to stir up the acorns which help make sure if any bad ones were trapped under the good ones they came to the top so we could remove them.

     

    Rinse the acorns for a few minutes to get any remaining dirt off of them. We used this stick to help disperse the water over the batch of acorns. Then let them soak to soften the shells so you can crack them open easier.

    Step 3 – Cracking Open the Acorns:

    • Once you have sorted the acorns and only have the good acorns remaining (the ones that did not float) drain all the water out of the sink.
    • After all the water is drained, rinse the acorns with the drain open for several minutes.  You do this by running the water through the acorns and stirring occasionally.  This step helps get out any of the extra dirt and cleans the acorns.
    • Plug the drain, refill the sink with water and let the acorns soak under water for approximately hour to soften the shell.
    • Once the acorns shells have softened take out an acorn, tap it lightly with a hammer until it cracks slightly, peel back the shell and remove the nutmeat.
    • Put the nutmeat in a pot that you can cook it in and put the shell in another bowl that will be taken back outside to compost or throw away.
    Cracking open the acorn with a hammer.
    • Tips to help cracking open acorns:
    • You can use a flat screwdriver to help pry open the shells.  Usually your fingers will work but sometimes having a screw driver helps.
    • You can start cracking open the acorns right away instead of soaking for an hour, however, you will notice that the longer a acorn has been soaking the easier the shell is to remove.  I just took out a handful at a time so the remaining ones could continue soaking.

    Step 4 – Processing the Acorns (AKA “Leaching” the tannins out of the acorns):

    • This step is very important with acorns.  You will need to leach the acorns to remove any tannins that are in them.
    • Bring two large pots to a boil.
    • Pour the acorns into one pot and let it boil for 15 minutes.  The water will turn a dark brown / black color which is the tannins coming out of the acorns.
    • After 15 minutes strain the water off the nuts and transfer them to the second pot of boiling water.  Boil them for another 15 minutes.
    • While the second pot of water is boiling with the acorns refill the first pot and bring it back to a boil.
    • Continue transferring back and forth from one pot of boiling water to the next for 15 minutes at a time until the water stays clear.
    • The nutmeat will not have a bitter taste to it once the tannins have been removed through leaching.

    • Tips to help with processing / leaching:
    • If you can use a large pot with a strainer inside it for transferring the nutmeats between the boiling pots of water it will be much easier.
    • Make sure to never rinse the nutmeats in cool water during the leaching (boiling) phase of the processing because it could actually cause the tannins to seal in the nutmeats making it impossible to remove enough of it so you can safely eat them.
    • It usually takes several boiling times before the water comes back clear.

    A dehydrator full of dried acorns! They will dry to a dark brown color.

    Step 5 – Drying the Acorns:

    • Once the water is clear after boiling the acorn nutmeat you can drain them completely and transfer them to a jelly roll pan, spread out into a single layer and bake for 1 hour at 350 degrees.  OR you could put the acorn nutmeat into a food dehydrator until the nutmeats is completely dry (approximately 8 to 12 hours).
    • The nutmeats will turn a dark brown color when they are completely dry.  You are now ready to try out your acorn recipes!
    • Tips to help with drying:
    • The dehydrator works really well for drying out the nutmeats.  It works a lot like drying fruit or beef jerky.  Plus it can run through the night and uses less power than your oven.
    • You can dry the acorns for several days in the sun but you take the risk of bugs and squirrels taking the acorns or they could go moldy.  It is pretty easy drying them in the oven or dehydrator so I think that would be the best option.
    • You can store the dried acorns for several months in the refrigerator or freezer, they will last several week at room temperature.

    I will be sharing soon a couple acorn recipes that we have tried with the acorns we have processed from our yard.

     

  • On the Farm: Acorns Are For Squirrels

    Rinsed acorn with its cap still on.

    “Acorns are for squirrels to gather and eat during the cool winter months” was my response when the kids asked me about the purpose of acorns.  It has been a pretty mild Fall in our area but our yard has been full of acorns, squirrels, birds, rabbits, turkeys, and all kinds of animals gathering for the cooler months.  Our family has been blessed to have property with a lot of trees, a small creek, and plenty of wildlife.  Even though we live in the “suburbs” on our little 4 plus acres it feels like we are out in the country.  One of the Fall activities we have as a family is raking leaves and acorns.  Now that the acorns and leaves are steadily dropping the discussion regarding Fall, leaves, acorns, and activities around the season have been in full swing on the farm.

    There are several oak trees on our property but the one in our front yard has produced an abundance of acorns this year (the ground was covered and continues to be covered with acorns even after raking and collecting).  After thinking about it for a little bit we concluded that the reason that tree was so full of acorns had to do with the extra “water” that is has enjoyed from our garden.  Jake and I were talking about the tree and the amount of acorns and jokingly mentioned that we could live off the acorns if we wanted to this winter.  The girls were already collecting acorns for their “acorn pies” they were making in the sandbox and asked us a couple times why we couldn’t eat acorns.  I honestly didn’t have a great answer other than my normal because “Acorns are for squirrels.”

    After a couple weeks of thinking about our conversation and talking with the girls about how people in the past lived off the land through gardens, nuts, animals, and crops I decided to research acorns a little more.   I figured that if the squirrels are eating the acorns there has to be some benefits to them, right!?  They are a nut.   I read what articles I could find about how to cook acorns and decided it may be fun experiment for the family to try making something with the acorns.  There is not a huge amount of acorn recipes out there but I was able to get enough to feel confident to try it.  I figured it would be an interesting educational activity for the kids as well.

    Here’s some fun facts about acorns that you may or may not know about:

    • The first people that we can find in history who have ate acorns were the Greeks over 2,000 years ago
    • The acorn has been a source of nutrition for many people during past food famines.
    • Native American Indian tribes use acorns.  The Cherokee, Pima, and Apache Indians considered the acorn a staple food that they used in a variety of recipes.
    • The majority of acorns cannot be eaten raw from the trees or ground.  They have a bitter taste which is the tannin that is used to make leather.  If you taste a raw acorn and it is very bitter it is best not to eat it until it has been processed.
    • There are a variety of ways people have used to remove the tannins from the acorns.  Some records show that they have buried the acorns in mud for weeks then will dig them up and use the sun to dry them naturally.  Others place the acorns in a basket or cloth (the basket or cloth needs to be strong enough to hold the nuts but allow water to run through it) with heavy stones, place the basket in a quick flowing stream for several days or weeks then they would sun dry them.  Now with stove tops the process of removing the tannins is quicker by boiling the tannins out of the acorns (I will go through the entire leaching of the tannins process in a later post).
    • It is said that a fully grown Oak Tree can produce as much as 1,000 pounds of acorns in one season.
    • Acorns are low in sugar and have a sweet nutty taste.
    • Acorn flour or meal can be used in bread, cookies, grits, pancakes, brownies, stews, cakes, tortillas, muffins, and many other recipes.  You can eat an acorn plain or with a glaze once it’s been processed.
    • Acorns have carbohydrates, protein and fats, 6 vitamins, 8 minerals (including calcium, phosphorus, potassium), and 18 amino acids.  They have a lower fat content than the majority of other nuts and compare very well with other wild foods you find in nature.
    • Eating 1 handful of acorns is like eating a pound of fresh hamburger (nutritionally equivalent)
    • Much like the squirrels storing acorns for later we can store acorns for a long time as well.  Acorns do not spoil quickly so they can be eaten and/or processed at a later time.

    There are two main types of trees acorns come from:

    • The White Oak Trees can live over 650 years, be more than 4 feet in diameter and up to 100 feet tall.  The White Oak is the most common and has a dark green glossy leaf with light green on the bottom and the leaf edges are rounded.  White Trees have a smooth shell and the nutmeat is a shade of white.  The White Oak Trees are the best for acorns that you want to eat and use in recipes because they have a low tannic acid, but are still sweet and can be eaten after a little processing.
    • The Red Oak Trees are not as common and their leaves have a glossy green top side (much like the white oak) but there bottom side is fuzzy and the leaf edges are pointed.  The Red Oak acorns can take up to two years to mature and the nutmeat is more of a yellow color.  Red Oaks require processing before to eating and generally are not harvested for human consumption unless there is a famine.   Red Oak Trees have a higher tanic acid level which is why they need more processing and are typically eaten when necessary such as starvation or famine because if you eat too much tannin it can be bad for your kidneys.

    Why do Acorns need to be processed before eating them?

    • Acorns contain tanic acid (if you try a raw acorn and it is bitter that is the tannin you are tasting) which is used to make leather and has several other great qualities, however, if you eat an excessive amount of tannin it could lead to kidney failure.  If you want to try processing and using acorns for recipes try to pick the acorns from a White Oak Tree since they are much lower in tannins; if you decide to consume ones from a Red Oak make sure to process them very well.  I will walk you through the steps to remove the tannic acid (tannins) from the acorns, the process is called leaching.
