Apple Fluff

The custard can be made up to 2 days ahead and stored covered in the refrigerator. Add a piece of plastic wrap pressed directly against the surface to prevent skin formation. The apple fluff cannot be made ahead as it will separate and deflate; prepare it just before serving.

This dessert is best served immediately and does not store well. The apple fluff will weep and collapse within hours. Leftover custard can be refrigerated in an airtight container for up to 3 days, but discard any assembled dessert after 2 hours at room temperature.
