A brief history of Acorns

There are probably some things you don’t know about acorns. Before we dive into the review of today, we will run through a brief history of acorns.

The purpose of sharing this is to ensure that you have a proper understanding of what you are getting a mill for.

Acorns are widely consumed by the wildlife that we depend on for nutrition. Wildlife such as birds like jays, pigeons, some ducks, and several species of woodpeckers feed on acorns.

These nuts are also consumed by mice, squirrels, and several other rodents.

Acorns appear large and efficient to animals mostly, and that is what attracts animals to them. They can be efficiently cached. Acorns are highly rich in nutrients.

We can not clearly state the percentages of nutrients that can be found in acorns as they vary from species to species. However, one can obtain nutrients such as protein, carbohydrates, and fats,  minerals calcium, phosphorus,
potassium, and the vitamin niacin when acorn is consumed.

But as we have mentioned earlier, the bitter tannins are significantly a factor for consideration when planning to grind and consume acorns as humans.

There is a lot of science to this but what you should know is that these tannins that are very much present in acorns are plant polyphenols, which means that they will interfere with a human ability to metabolize protein.

If you are going to consume acorns, you should learn the different ways to use the nutritional value contained by acorns.

Tannins present in acorns should not blindfold you to all the nutritive benefits of consuming arcons.

By soaking chopped acorns in several changes of water, until the water no longer turns brown, or by making use of Coldwater leaching which may take several days, you can get rid of or reduce the tannins present in your acorn such that they will now become very safe to eat.

Acorns are rich in fat and can mold easily. if you are going to grind acorn, you need a unique hand-powered grain mill that will give you the healthy result you want after leaching them.

We have considered this and have come up with the best grain mill for acorns. While we will still share with you the process of grinding and preparing acorn that is safe to use, let’s quickly examine if truly, they are safe for consumption.

How safe is acorn for consumption?

Best Grain Mill for Grinding Acorns

When prepared properly, and the tannins in them is reduced, acorns are safe for consumption. They can be ground to make flour for bread, pancakes, pastries, cookies, and even pasta.

To make acorns safe for consumption to make flour, we recommend you to leach with cold water to preserve the starch.

To get rid of the harmful tannins present in acorn that makes them unsafe for consumption, just use hot or cold water to leach them.

Your choice of the temperature of water to use will depend on your planned recipe.

The process of leaching with either cold or hot water involves, first, shelling your acorns, soaking them in the hot or cold water, draining the water once it turns brown, and repeating the process with fresh hot or cold water until the water is clear.

We will still go into details on how this is done, measurements, and duration for soaking. But, for now, let’s dive into the best grain mill for grinding acorns.

Our guide for grinding Acorns

We can tell you that it is not a difficult task to make flour out of acorns. It can be a little tricky for beginners and time-consuming too. But we are sure that these steps below will help you greatly.

Putting the acorns together

Needless to say, the first step involved in grinding and preparing flour out of acorns is gathering them in the right proportion. Depending on the volume you plan to work with, you may choose to gather up about a gallon of acorns.

It would also be better when we are in the season where they are available in abundance from oak trees.

Removing the Caps of the nut

Now that you have gathered up your acorns, the next thing to do is to remove the caps from the nuts. This is a really easy thing to do and you don’t need any one-hour duration youtube video to show you how this is done. It may be time-consuming, though.

Shelling the Acorns

The shelling process of the arcons contributes to the process of getting rid of the harmful tannins compound present in them that is not safe for consumption. Shelling can require either hot or cold water depending on your planned recipe as we have explained earlier.

When shelling your acorn, you have to first put the acorns in the freezer overnight so that it will be easier to crack them and they will be kept fresh.

After freezing, the paper-like membrane around the nut and inside the shell will come off the nut. You also want to make sure they are thrown into water before they turn brown because, at this stage, they tend to oxidize quickly.

Blending the Acorns

Any durable countertop blender with the right attachment for grinding nuts will do. All you have to do is move the water containing the nutmeat into a blender.

At this stage, the acorns have been shelled, so you can blend on the high for some minutes.

Leaching the Tannins in the acorns

This is one of the most important steps of all that should not be missed. After you have blended the nutmeat, transfer the result to a bowl that is wide enough to contain all the blended stuff, and then put it inside the fridge until the next day. Doing this will allow the acorn to settle and allow you to pour off the water in the container.

Continue this process with fresh water and place it inside the fridge again. Doing this for about three days will successfully leach out the bitterness of the acorn. They taste bitter, but this is the best way to get rid of that bitterness.

Grinding the Paste in a grain mill

We recommend the use of any of the grain mills shared in this article as they are all perfect for this process. If you can’t afford a grain miller, a food processor is another alternative.

Use the grain mill to grind the acorns into flour because they will be clumpy. By grinding them properly, you should get fine flour. If there are still larger chunks, you may need a mortar and pestle to further break them down.

Sifting the Flour… and sifting again!

You now have your fine ground acorn flour, thanks to a capable grain mill. The next thing is to get rid of any debris by separating them from the flour, this is done by using a fine-mesh sieve to sift. Sift and sift till you can see that it is smooth.

You can now decide on what to use the cups of flour made from acorns.
