To make your own applesauce, peel and core apples, then put in a small saucepan with enough water to cover the bottom. Bring to a boil and simmer, checking the water level to make sure that it doesn't boil dry. You will need to add some now and then. Continue to simmer the apples until they are soft, then pull off the heat and mash with a potato masher. Set the sauce aside and let it cool before using in the recipe.
