Because black mulberries are strong against pests, you can preserve them in the fridge or you can dry them to use later on. This fruit is a great antioxidant and a great boost for the immune system. Black mulberry mollases, pectin and "pestil" (dry paste) are commonly found in Turkey. It may be difficult to make these because they need a great deal of boiling, but with this recipe you can easily make black mulberry marmelade at home.
