Cut apples into wedges (or use an apple slicer, corer, and divider to speed up the process). Fill the Instant Pot two-thirds full of apples.
Add 1 cup water (½ cup for a 3-quart Instant Pot.) Lock the lid in place and set for 3-5 minutes. (Time will vary depending on the hardness of the apples and how thinly they are sliced.)
Let the pressure release naturally for 15 minutes. Release any remaining pressure. Carefully remove the lid. Process apples through a food mill to remove peels and seeds.
Serve warm. Cover and refrigerate up to 1 week, or freeze up to 1 year.
