Clean the cherries, remove the stems and pits.
In a saucepan, place the cherries cut into small pieces, add the lemon juice and sugar (and vanilla or some mint leaves).
Heat over medium heat for 10 minutes, stirring occasionally so cherries do not stick and cook evenly.
At the end of the cooking time, (remove the mint leaves) mix everything together and let it cool.
Place the cherry puree in your ice cream maker and turn it on for 15 minutes (or follow your machine's instructions).
Place the cherry sorbet in a tray and set aside in the freezer. When ready to serve, remove the sorbet 5 to 10 minutes ahead of time and enjoy.
