Spray an 8x1-1/2-inch round baking pan or 8-inch ovenproof skillet with nonstick cooking spray. In a mixing bowl beat together the eggs, flour, milk, and salt with a rotary beater until thoroughly mixed. Pour into the prepared pan or skillet.

Add the brown sugar; apple juice, apple cider, or water; half-and-half, light cream, or whipping cream; apple brandy or orange juice; and cinnamon or apple pie spice. Bring to boiling. Reduce heat simmer for 2 minutes, stirring occasionally. Remove from heat. Stir in the walnuts or pecans.
