Pit the cherries.
Put them in a bowl with the sugar and wine.
Put them in the fridge for at least 1 hour, but it is recommended to leave them for 24 hours.
Cook them over low heat in a non-stick pan until the liquid reduces a little. Not too much. Don't make it thick. Mash them a little with a masher during cooking.
Blend them with a hand blender. If it is a little thicker than expected, you can add a few drops of water while still hot.
Let it cool.
Enjoy!
