Whole oat groats are the result of simply harvesting oats, cleaning them, and removing their inedible hulls. This form of oats is far more nutritious, and the texture and taste is superior then its counterparts that have been heavily processed. They offer up a strong, nutty-oat flavor.
Oats do not actually contain gluten, but they are often grown alongside other gluten containing grains, therefore many people with celiac disease cannot eat them. However, those with celiac or gluten intolerance can still enjoy oats as long as they are certified gluten-free oats. Oats contain a protein called avenin which is can trigger an immune response similar to that of gluten in some people with celiac disease. Proceed with caution if this is an issue for you.
Oats are a rich source of soluble fiber, protein and vitamins, and a great way to help reduce bad cholesterol. And the best method to get their full nutrition is to mill (grind) some as needed. You can go ahead and do the soaking and dehydrating process, having it all ready to go for those times that a recipe calls for oat flour.
Further on down the post, I share with you three different kitchen tools that can be used to create oat flour. There are other units out there besides these, but these are the ones that I have in my personal kitchen.
The first one that I used was the Dry Grain Container that fits the Vitamix blender. The dry blades are shaped to push ingredients up, in order to minimize packing into the bottom corners. Is this unit a “must have”? Not really, you can use the standard blender container if you don’t own the dry grain container. If that be the case, why invest in the dry container? Grinding very hard items like grains can possibly scratch the inside of the container near the blades. This can cause a“cloudy” marring of the plastic, and the scratches make it more likely to hold smells over time.
Next, I used the Magic Bullet. If you own one of these, you know that it comes with two different blade lids. For creating flours, you want to use the flat bladed lid. You can only do about 1/2 cups worth of oats at a time. After activating the bullet, blend for about 30 seconds, then stop, shake the unit and blend again. Stopping and checking to see how fine the flour is getting.
Lastly, you can use a coffee grinder. This is the least expensive unit to purchase, the drawback is that you have to do small batches at a time. I recommend only filling the grinder about halfway in order to produce a more even grind. The length of time you grind will affect the coarseness of your flour. The longer you grind, the finer it will be.
Regardless of what device you use, if you want a really fine flour, sift it through a fine mesh sifter and then regrind the larger bits that don’t pass through. Repeat this process until everything is finely ground. I hope that you found this helpful and that I have encouraged you to try your hand at making your own oat flour. Blessings, amie sue
