Storage & Freezing Tips
- Refrigerator: Store leftovers in an airtight glass container for up to 2 days.
- Reheating: Warm gently in a skillet on medium-low heat with a lid to keep the fish tender. Avoid microwaving to prevent rubbery texture.
- Freezing: We do not recommend freezing cooked fish as it degrades the texture.
