We have some black walnut trees here on the farm planted by a previous owner and my husband decided to harvest some this year. The pecan trees had a bad year. He picked a lot of walnuts and put them in the driveway. It is a good way to hull them without so much work. Run the car over them and later pick them up sans hulls. That is where you can get your hands stained. Cure them in a cool dark place for a couple weeks. Then comes the hard work. The shells are quite hard! You need a hammer to crack, and then picking out the meat you need a nut hook and more time. No wonder these nuts command a high price in the store. One source says storing the hulled walnuts for a couple months makes the nut meat shrink some and therefore easier to get out. If you are not going to use the walnuts soon they can be stored in the freezer.

My mother used them in cakes but we are more into savory than sweets. I looked through my many cookbooks but didn’t find any recipes even for sweets. Rosalind Creasy did write about them in her book, The Gardener’s Handbook of Edible Plants. She talks about the black walnut, Juglans nigra, which we grow. Most people like and eat the more familiar Persian (or English) walnut, J. regia. She mentions two more: butternut, J. cinerea and California black walnut, J. Hindsii.

She says black walnuts, like okra, gooseberries, and rhubarb are an acquired taste. Their flavor is quite strong and distinct. I like it and use it in my salads. It adds an extra flavor in a fruit cake.

I wonder why they do not appear more in Southern cooking as they would be available to the harvester for free, like other wild foods. Certainly the wood was used in Southern furniture.

If you choose to plant, the trees are nice for shade, but are not for small tailored yards. Ours grow in the pastures. Also of note, the roots exude an acid that inhibits the growth of many plants. Keep them away from vegetable gardens, flower beds, azaleas. They can be grown even as far north as Ontario and south to northern Florida and are native to the eastern US. Although the deep South is not part of their natural range, they certainly grow well here is south Mississippi.

They have omega-3 fatty acids and are heart healthy and are rich in antioxidants. They also have antifungal properties.

I did find a savory recipe for black walnuts and shrimp. It is basically a stir fry but instead of peanuts or cashews, black walnuts are used instead.
