A spicy gingerbread muffin from a 1931 magazine ad.
Mix and sift all dry ingredients
Add the sour milk, molasses, melted shortening, and egg.
Mix thoroughly. Pour into greased muffin tins. You can also use paper muffin cups, but mine did release just fine from a greased pan.
Bake. Original Instructions say 360 degrees for 27 minutes. I suggest beginning to check for doneness at 15 minutes. When a toothpick inserted in the center comes out clean they are done.
