This is the best I've made. It tastes like the ones I have tried at Chinese restaurants.
INGREDIENTS (for 4 servings):
- 1/2 cup rice vinegar
- 1/2 cup white sugar
- 1 clove garlic, minced
- 1/4 teaspoon salt
- 1 1/2 teaspoons dried red pepper flakes
Bring the vinegar to a boil in a small, non-reactive pot, and mix in sugar until dissolved. Reduce heat to low, simmer 5 minutes, and remove from heat. Mash the garlic and salt into a smooth paste, and mix into the pot. Stir in the red pepper flakes. Cool to room temperature before using, or store up to 2 days in the refrigerator.
