These were quite nice!! I added the grated cheese as suggested and they were so good. Trying to get the coarse crumby texture required adding almost another 1/3 cup of shortening. When making up the dough, I wasn't sure if I had enough buttermilk in it after using 2/3 of a cup. The dough seemed a bit dry still. But when they cooked up, they were the perfect texture.
These are very dry and hard to swallow unless you saturate them with butter. The flavor is pretty good, though, and these would be excellent if covered with gravy. I wouldn't suggest eating them without a large glass of milk nearby.
