In a large saucepan, saute onion in butter until tender. Add garlic; cook 1 minute longer. Stir in the remaining ingredients. Cook, uncovered, over medium-low heat for 20 minutes or until cherries are tender and sauce is thickened, stirring occasionally.
My Note: I Purchased the Taste of Home Grill It cookbook and this was one of the recipes I've tried. Made a double batch with fresh bing cherries. The only change made was adding a little kick of heat with an Italian red pepper. EXCELLENT on BBQ whole chicken breast. Will be making an another double batch and canning for future use.
I like it a little spicy, so I added some sweet hot Asian pepper sauce to it. Finger licking goodness.
