Sift together 1 cup flour, 2 teaspoons baking powder and a pinch of salt. Add 1/2 cup sugar, 1 cup raisins and 1/2 cup milk. Combine and put into a greased pie dish. Mix 2 tablespoons treacle, 2 cups boiling water and 1 tablespoon butter. Pour this sauce over the batter and bake in a moderate oven about 1/2 hour. As the batter rises, the sauce drops into it and moistens the batter.
