You can make a delicious and healthy dessert from quince and banana in 10 minutes. Quince is rich in antioxidants and supports the immune system. Bananas strengthen the walls of blood vessels and have a beneficial effect on the nervous, digestive and cardiovascular systems. Choose ripe fruits. The quince should be yellow, dense, but not stone-like. A subtle light aroma emanates from the ripe fruit. The skin of bananas should be without tears or dark dents; small dark spots are a sign of ripeness.
