Use this to make our Applesauce Muffins and Applesauce Coffee Cake.
Bring apples and cider to a boil in a medium saucepan over medium-high heat. Cover pan; reduce heat. Simmer until apples are very soft, about 12 minutes. Remove lid; stir in sugar and salt.
Cook over medium-low heat until apples are broken up and most of the liquid is evaporated, about 15 minutes. Let cool slightly. Blend in a food processor until smooth. Add more sugar if desired.
Store in an airtight container up to 2 days.
