Grilled Chicken Breasts with Grapefruit Glaze

I make this recipe alot, and I am suprised I haven't added it to my blog earlier. I love the grapefruit flavour with the chicken.  This recipe was taken from Food and Wine's Magazines's "Quick From Scratch Chicken Cookbook".

1 teaspoon grapefruit zest (from about 1/2 grapefruit)
2 cloves garlic, minced
1/2 cup grapefruit juice (from 1 grapefruit)
1 tablespoon cooking oil
2 tablespoons honey
1/2 teaspoon salt
1/4 teaspoon fresh-ground black pepper
4 bone-in chicken breasts (about 2 1/4 pounds in all)

1.  Light the grill.  In a small bowl, combine the garlic, grapefruit zest, grapefruit juice, oil, honey, salt and pepper.
2. Grill the chicken breasts over moderately high heat, brushing frequently with the glaze, for 8 minutes.  Turn and cook, brushing with more glaze, until the chicken is just done, 10 to 12 minutes longer.  Remove.
3.  In a small stainless-steel saucepan, bring the remaning glaze to a boil.  Boil for about 1 minute, remove from the heat, and pour over the grilled chicken.
