Storage and Reheating Tips

Store the custard slice in an airtight container in the refrigerator for up to 3 days. For best texture, serve chilled. Avoid reheating as the custard may lose its consistency; instead, enjoy directly from the fridge. If needed, allow it to sit at room temperature for a few minutes before serving for a softer texture.
