1 cup of tomato sauce1/3 cup light corn syrup
1/4 cup white vinegar
2 teaspoons dry onion flakes
2 teaspoons granulated sugar
1 teaspoon salt
1 teaspoon lemon juice
1/8 teaspoon garlic powder
Whisk everything together and bring to a boil in a small saucepan with a heavy bottom. Turn heat down to a low simmer and cook for 25-30 minutes, depending on how fast you are simmering it (mine was done in 25 minutes). Watch it towards the end so it doesn't scorch.
Cool to room temperature, then cover and chill.
