Remove the label from the can. Place unopened can at the bottom of a deep pot. Fill pot with water so it is 4 inches above can lid. Bring water to a boil and boil steady for 1-1/2 hours.
Ensure the can is always covered with water. Do not allow the water to get so low to expose the top of the can; this could cause the can to explode. Add water as needed.
Refrigerate to cool. Pour cooled sauce into a bowl, add dairy whip and stir until well combined. Serve with sliced apples.
Tip: It’s also suggested to boil three or four cans at once and save them for later.
