One quart of corn meal; one teaspoon full of salt; one tablespoonful of melted lard; one large cup of boiling water. Melt the lard in the water. Mix the salt with the meal, and pour on the water, stirring it into a dough. When cool, make either into one large oval cake or two smaller ones, and bake in the oven to a bright brown, which will take about half an hour; or make in small cakes, and bake slowly on a griddle, browning well on each side. Genuine hoe-cake is baked before an open fire on a board.
