Living around so many farms and having grown up on a farm with apple trees, making apple sauce on the fly has become second nature to me. I use applesauce namely for baking, although I do love to have a small bowl of chilled applesauce as a snack. Apple sauce is also used as the base for making fruit leather and the fruit leathers never last very long with my 2 kids.
Here is how I make a quick, small batch of apple sauce.
3 lbs tart apples
1 cup water
1/2 cup sugar
Wash the apples. Peel, core, and quarter the apples. In a large pot, add the apples, water, and sugar. Cook on high just until the water boils then turn the temperature to medium low. Stir, making sure the apple does not stick or burn to the bottom. Once the apples are soft, remove from heat and either mash with a potato masher or but through a blender. Refrigerate in a closed container and use as needed.
