3 cups cider vinegar
3/4 cup tomato ketchup
6 Tbs. light brown sugar
3 Tbs. granulated sugar
1-1/2 Tbs. kosher salt
2-1/4 tsp. finely ground white pepper
2-1/4 tsp. red chile flakes
3/4 tsp. freshly ground black pepper
In a medium bowl, whisk all the ingredients together and let sit for at least 10 minutes. The longer the sauce sits, the hotter it gets, as the vinegar brings out the heat of the chile flakes (so start with the amount of chile flakes called for and then add more to taste). Pour the sauce in a vinegar style bottle so you can pour and store it easily. It will keep almost indefinitely in the refrigerator.
