Storage Options
Store leftover puffs in an airtight container in the fridge for up to 4 days. To reheat, pop them in a 350°F oven or air fryer for about 5–8 minutes to regain their crispiness. These also freeze well—just freeze them on a baking sheet, then transfer to a freezer bag. Reheat straight from frozen.
