Wash the peaches and cut them in even slices.
Wash the jars very well, with dish soap, and rinse until the water comes clear. Alternatively, wash them in the dishwasher.
Add the sliced peaches to the jars, three-quarters up.
Add 2-3 tablespoons of sugar over the peaches, in each jar.
Complete with water until you cover the peaches.
Seal the jars with the lids.
Put a tea towel at the bottom of a pot, and put the jars inside.
Fill with cold water until the jars are ¾ submerged.
Cover with another tea towel and turn on the heat on medium.
When the water starts boiling, set a timer for 10 minutes.
After 10 minutes, turn the heat off.
Take the pot off the heat and let the jars cool down slow, inside the water, preferably overnight.
The next day, take the jars out and put them upside down for a couple of hours, before storing them in your pantry.
You can enjoy the peach kompot either cold, as a refreshing drink on a hot summer day, or you can warm it up, on a cold winter day.
