Sweet quince

For this delicious sweet we need 300 g of quince, 1 kg of sugar and half a liter of water.
It is easy to prepare. First peel the quinces and put into the water to not get a dark color. Plane them.
We put the sugar and water to cook until it thickens slightly. In that we put grated quince and cook 7-10 minutes .
We pour sweet in jars.
