What is barley anyway?
Barley is a whole grain that is harvested from a plant in the grass family. It has a somewhat chewy texture, which gives it a satisfying feel in the mouth, and a slightly nutty flavor. It’s used often as an addition to soups and stews, and is also used to create a malt for beers and other alcoholic drinks.
It’s nutritional makeup is about 17% fiber, which is one of the highest of all the whole grains. Like oats, it also contains high levels of soluble beta gluten fiber, which helps to control blood sugar. It’s also an excellent source of manganese selenium and vitamin B3, while also being a good source of protein.
If you haven’t tried adding barley to your diet, now’s a great time to start!
Is barley gluten free?
A word of caution to my gluten free friends, barley is not gluten free. If you still would like to make this soup, buckwheat or amaranth would be a good alternatives, but it may require adjust the cooking time a bit.
Should I cook this on the stovetop or my Instant Pot?
I prefer to cook this in my Instant Pot, simply because it is a bit faster and lower maintenance. However, it doesn’t take too long on the stovetop, so that works as well. If you decide to cook on the stovetop, the barley will take bout 45-55 to soften after it has reached a boil.
If you choose the Instant Pot, it cooks in 20 minutes, with an additional 10 minutes of natural release. After the time it takes for the IP to come to pressure, it’s not that much faster. However, I still prefer this method because you can just set the timer and walk away.
Do I need a high speed blender?
A standard blender will work well. I would recommend soaking the cashews for an additional 10 minutes, so 30 minutes total if you use a standard blender. There should be plenty of time to soak the cashews for both methods, after the soup starts simmering or cooking in the Instant Pot.
Happy Cooking!
