Add the water and sugar in a 5-liter pot (so that the Kompot does not flow over the sides) and bring the water to a boil.
Next, add the berries, bring to a boil once more, and simmer everything on low heat for about 10 minutes. Finally, remove the pot from the stove and leave it to rest and cool down for about 30 minutes.
You can enjoy the Kompot warm or cold (with or without ice cubes).
