I just saw a video on how to make Grilled Raspberry Glazed Chicken Breasts. She put the glaze on the chicken immediately after putting it on the grill at medium heat. The finished product looked good but I thought you are supposed to glaze at the end for only a couple of minutes. Will the glaze burn if put on too early? The glaze was 1/2 cup raspberry Jam and about 1 Tbls. yellow mustard.
