Storage & ReheatingCooked nuggets will keep in the fridge for up to 3 days in an airtight container, or in the freezer for up to 2 months. Reheat in the oven or air fryer at 180°C (350°F) for 8-10 minutes, until hot through and crispy again — the microwave will make the coating go soggy. The umami mayo contains raw egg, so use a pasteurised egg where possible, particularly for pregnant, elderly, very young, or immunocompromised eaters. It'll keep in the fridge for around 5-7 days rather than the couple of weeks you'd get from a shelf-stable, store-bought mayo.
