Put the cooked cakes in a shallow container and refrigerate promptly at 4°C (40°F) or below, within 2 hours of cooking, or within 1 hour if the room is above 32°C (90°F). Cover once chilled and eat within 2–3 days. To freeze, separate the chilled cakes with baking paper and seal in a freezer bag. Thaw in the refrigerator, then reheat in a frying pan or microwave until the centre reaches 74°C (165°F).
