Ingredients
1-3/4 cups ketchup
1/2 cup plus 2 Tbs water
1/4 cup plus 1 Tbs cider vinegar
1/4 cup plus 1 Tbs white vinegar
1/4 cup plus 1-1/2 tsp brown sugar
2 Tbs plus 1-1/2 tsp Worcestershire sauce
1 Tbs chile powder
1 Tbs ground cumin
1-1/2 tsp kosher salt
1-1/2 tsp coarse black pepper
Preparation
Combine all ingredients in a saucepan and warm gently over medium heat, stirring occasionally. There is no need to bring the mixture to a boil, as the idea is just to warm it enough to melt and integrate the ingredients. Once you have done that, remove from the heat and let cool. Transfer to a jar, bottle, squeeze bottle, or however you want to store it. Store in the refrigerator for up to 1 month.
