White currant jam for winter

Remove the white currant from the twigs, wash and dry on a paper towel (ordinary is also suitable). Use a juicer to prepare the juice. For those who have not yet had time to purchase a juicer, grind the currants through a sieve. Approximately 1 - 1.3 liters of juice will come out of 2kg. currants.
Pour the finished juice into a bowl in which we will cook jam, add sugar, mix and put on medium heat. As soon as the jam boils, reduce the heat to the minimum that is possible on your stove and cook for 30 minutes. Do not forget to stir the jam and remove the foam during cooking.
Pour the hot jam into sterilized jars and roll up the lids. Cool under a blanket, put away for storage in a cool place.
