Storage: Refrigerate leftovers airtight up to 3 days. Re-crisp in a 375°F (190°C) oven for about 10 minutes. Freezing: Freeze uncooked breaded sticks on a tray until solid, then transfer to a freezer bag up to 3 months; fry from frozen, adding 2–3 minutes. Oil temp matters: too low = greasy, too hot = burnt outside before the fish cooks.
