Mississippi Cake (1860) One pint of the best yellow cornmeal, a pint of buttermilk, two tablespoonfuls of melted butter, two eggs, a teaspoonful of salt, and a teaspoonful of saleratus. This cake sounds like some good cornbread, even if called a cake. The recipe is from "Civil War Recipes Receipts from the Pages of Godey's Lady's Book". Note: Saleratus: Soda bicarbonate (baking soda). It was introduced about 1840. It required the addition of cream of tartar to work.
