Sweet and Sour Sauce

This is a recipe that I've been using since I was about 9. We learned how to make Hawaiian Haystacks at a church activity and used this sauce. I also use it to top sweet and sour meatballs.

Sweet and Sour sauce:
mix:
1 cup brown sugar
1/2 tsp garlic
1/2 tsp ginger (I usually add more of each ginger and garlic though)
2 Tbls. cornstarch
then add:
1/2 cup apple cider vinegar (white works though)
1/3 cup pineapple juice
1/3 cup water (you can add more water and less juice or more juice less water to adjust sweetness)
2 tsp soy sauce

microwave for 4-5 minutes until thickened
