"This is one of my favorites. The recipe came from Eagle Mills. If you don't have buttermilk, you can substitute 1 cup milk plus 1 teaspoon cider vinegar, and let it sit about 10 minutes before using. You can also add 4 tbs. buttermilk powder to the dry ingredients and substitute water for the buttermilk. I have also used plain all-purpose flour with excellent results...."
