This Sweet and Sour Sauce recipe goes along with one of my favorite Chinese-American dishes: sweet and sour chicken! This homemade sweet and sour sauce is so tangy and tasty. I love slathering this sauce all over chicken, pork, or rice and vegetables. You can't go wrong!
Mix together pineapple juice, water, vinegar, sugar, ketchup, pepper flakes, salt and soy sauce in a medium saucepan. Set the pan over medium-high heat and bring to a boil.
Set heat to low and simmer until the sauce reduces to 1¼ cups, approximately 6-8 minutes.
Stir together cornstarch and water, whisk it into the sauce and cook 1 minute or until the sauce has thickened. Transfer sauce to a heatproof dish.
If not using immediately, allow the sauce to cool to room temperature and then refrigerate, in an airtight container, until ready to use.
