A tough nut to crack: Unlock the healthy benefits of black walnuts

Nutritious, delicious black walnuts
Posted by

When I was growing up, we had an old black walnut tree next to our driveway that would drop walnuts, causing me to trip over them while chasing my brother. I loathed this tree, especially when it was my turn to mow the grass, as I had to first rake the walnuts, wasting more of my precious time. Little did I know that we could have used these annoying nuts for delicious food. However, they’re a hard nut to crack.

If you’re determined enough to remove the husk from black walnuts (hop in your vehicle and drive over them a few times…yes, seriously) as well as the hard shell (forget the nutcracker and grab the hammer), you’re left with a nutritious nut with a richer, earthier flavor than the English walnut. Black walnuts have the highest protein content of any other tree nut with 15 grams protein per ½ cup. Plus, they’re an excellent source of omega-3 alpha-linolenic acid, an essential amino acid with multiple health benefits that the body cannot make on its own.

Storing and using black walnuts

Due to the oil content of the walnut, it’s best to store the nutmeat in a sealed, airtight container in the refrigerator for 9 to 12 months or in the freezer for up to two years. Use black walnuts in baked goods, such as cakes, breads, or cookies, and in other sweets like ice cream. Black walnuts may be substituted for other nuts and used in salads, pasta, or stir-fries.

If you don’t have a black walnut tree growing in your yard, or you’ve just given up the fight to get to the nutmeat, look for local hulled black walnuts at farmers markets, food co-ops, or online.
