Storage & ReheatingThese will keep in the fridge for up to 4 days, wrapped individually or in an airtight container. They also freeze well for up to 2 months — wrap tightly in foil or freezer-safe wrap before freezing. The tomato relish keeps separately in the fridge for up to 3 weeks in a sealed jar, or can be frozen for up to 3 months. To reheat, wrap in foil and warm in the oven at 180°C (350°F) for 10-12 minutes, or microwave for 1-2 minutes, until heated through. If reheating from frozen, thaw overnight in the fridge first.
