How to Make It
In a medium saucepan, combine the vinegar, sugar and 1/2 cup of water and bring to a boil over high heat. Add the cherries and return to a boil, then simmer over moderately high heat for 2 minutes. Remove from the heat and let cool completely. Transfer the cherries and brine to a 1-quart container and refrigerate overnight. Drain and pit before serving.
