Combine all of the ingredients into a medium saucepan and give it a quick stir.

Place over medium-high heat and allow to come to a low (small bubbles) simmer, while stirring occasionally.

Once at a simmer, cook for 8-10 minutes, until all the sugar has dissolved and the cherries have softened.

Remove from the heat and let stand five minutes.

Next, smash the cherries in the pan with a potato masher and then strain over a sieve set over a medium sized bowl.

Allow to cool completely. Transfer to a covered container (I like using an old jam jar) and chill.

Keeps for 7-10 days.
