After many attempts at getting the right orange chicken combination I discovered that the secret to making the best orange chicken is in the sauce. The best recipe I have found consists of combining 1 cups of water, 2 tablespoons orange juice, cup lemon juice, 1/3 cup vinegar and 2 tablespoons of soy sauce and bringing it to a boil. Stir in 1 tablespoon grated orange zest, 1 cup packed brown sugar, teaspoon minced ginger root, 2 tablespoons chopped onion, and teaspoon red pepper flakes. Bring the mixture back to a boil and then remove it from heat and cool for about 15 minutes. After marinating your chicken in 1 cup of sauce for 2 hours , coat and brown it on both sides then se to the side. In a skillet bring the sauce to a boil over medium heat. Mix in 3 tablespoons of cornstarch and 2 tablespoons of water. This is going to thicken the sauce. Reduce the heat and add in the chicken pieces. Simmer until everything is nice and hot stirring it occasionally. This makes the most delicious orange chicken and you will have people asking you for the recipe.
