A double-hit of orange comes from orange juice concentrate and fresh orange zest.
Combine vinegar, orange juice concentrate, soy sauce, oil, garlic, orange zest and thyme in a small bowl. Use 1/2 cup to marinate pork, chicken or shrimp. Reserve remaining marinade for basting.
People with celiac disease or gluten-sensitivity should use soy sauces that are labeled "gluten-free," as soy sauce may contain wheat or other gluten-containing sweeteners and flavors.
