Recipe tips The mozzarella will keep in an airtight container for a week in the fridge. Any leftovers would be great on pizza, stirred through chopped tomatoes or on flatbreads with falafel. Use the marinating oil in salad dressings or for roasting veg in. Keep it in the fridge and use it within a week.
