This is the marinade I made for chicken. I used it on boneless skinless chicken breasts and left them in the marinade for an hour.
Blood Orange Marinade
2 tbsp. blood orange juice
2 tbsp. balsamic vinegar
1/2 tsp. kosher salt
1/2 tsp. fresh ground black pepper
1/4 tsp. dried granulated garlic
Mix all the ingredients, place in large resealable plastic bag with chicken. Gently run into the chicken and set aside for at least 30 minutes before grilling. Shake off excess marinade before placing on the grill.
