This is a classic recipe.
You can make it to put on meatballs or for chicken wings.
Monica's Sweet and Sour
1 cup brown sugar
1/4 cup flour
1/4 cup vinegar
1¢ cup soya sauce
1 Tbsp ketchup
1/2 cup water
Mix them all together. Put your meatballs or chicken wings into a 9x13 pan and pour the sauce over it. Bake at 350ยบ for 15 minutes for meatballs and 25-30 minutes for wings. (but turn your wings over half way thru.)
Easy peasy.
