Quince has many beneficial properties: it fights stress and aging due to its high concentration of antioxidants, regulates blood cholesterol levels and accelerates metabolic processes due to its high pectin content. But you cannot eat it raw: it is very hard and sour. Therefore, jam and candied fruits are prepared from quince, but during hot processing, some of the healthy substances are lost. Try preparing just quince with sugar, and then adding it to tea instead of lemon.
