This applesauce is delicious served with our Potato Latkes.
In a large bowl, toss all the apples with lemon juice, and set aside.
Melt butter in a large skillet set over medium-high heat. Sprinkle sugar over melted butter; cook until sugar begins to brown. Add apples; cook until they turn golden brown, about 8 minutes. Stir in cinnamon and salt; remove skillet from heat.
Place apple mixture in the bowl of a food processor; process until smooth. Store in an airtight container, refrigerated, up to 3 days. Serve warm or at room temperature.
