How To Preserve Cherries, low sugar
1-2 tablespoons granulated sugar for each jar
Clean the jars thoroughly and sterilize them.
Pitt the cherries but leave them whole.
Add the cherries to the jars leaving about 1 inch of space at the top. Add 1 or 2 tablespoons sugar to each jar (to taste).
Pour water in each jar to completely cover the cherries. Seal the jars.
Take one very large pot. Place a clean kitchen towel inside. Put so many jars in the pot as they fit, taking care that they don't touch each other. Pour warm (but not too hot water) in the pot. The jars should be halfway immersed in the water. Bring the water to a boil and boil the jars for about 15 to 20 minutes.
Take the jars out immediately and leave them to get cold. Store in a cool, dark place (I keep them in the cellar).
I have cherries that I preserved using this method 2 years ago. They are still great.
