Firm, unripe apples are best for canning. These fruits will retain their appearance well.
Rinse the prepared fruit under running water and remove any leaves. Only fruit that is free of damage, defects, dents, or signs of pest activity should be preserved.
Next, place the apples in the sterilized and still-warm jars. Place the apples as close together as possible.
Pour boiling water over the fruit, cover the jars with a special nylon lid with holes and leave everything for half an hour.
After the allotted time, drain the water from the jars into a separate container in which you can make the syrup. Add granulated sugar to the drained water and cook until it is completely dissolved.
Pour the prepared syrup into each jar containing the preparation, close the containers with tightly sealed lids, and turn the jars upside down.
Wrap the resulting jars tightly and let them steep under a lid and blanket until completely cool. Then remove the blanket or towels, turn the jars upside down, and store them in a cellar, pantry, or kitchen cabinet.
