I found it is all rather simple and quick, if you have a cherry pitter, to prepare the cherries for grilling. Well, you really aren’t grilling the cherries per se. You don’t put each little cherry half on the grill. Rather, the grill or bar-b-que is the heat source to slowly simmer the cherries in the balsamic vinegar. It’s pretty effective and you don’t heat-up or smell-up the house in the process.
