Beeswax wraps are pieces of cotton coated with beeswax, often with plant oil and tree resin. The warmth of your hands softens the wrap so it moulds around a bowl, half an avocado or a block of cheese.
They are washed in cool water with mild soap and air-dried. Makers generally advise against using them with raw meat or hot food, and they gradually lose their grip with use. Plant-wax versions are available if you avoid animal products.
