Choose cherry fruits especially carefully, as one rotten berry can start fermentation. Rinse the selected fruits several times with cold water or soak them for 5-7 minutes in a basin. Remove the stems and seeds, being careful not to damage the berries too much. Prepare jars for storage.
Prepare the berries. Cover the cherries with sugar and citric acid, which will help preserve the natural sourness of the product. Place some air-permeable gauze over the container and leave until the juice is completely released and the sugar is dissolved, about 3 hours. Shake the berries periodically.
Sterilize the workpiece. Transfer the finished berries to jars, filling them with their own juice. Cover the preparations with lids, but do not seal tightly. Place a towel on the bottom of the pan, place jars on top and fill them with water. Wait until it boils, then sterilize the jars for 10 minutes. Then screw the lids tightly, turn the pieces over and leave to cool.
Use sweet cherry preparations in their own juice to make pies and desserts.
