Mom's BBQ Sauce

Mom's BBQ Sauce 1 1/4 cups ketchup 1 cup dark brown sugar 1/4 cup molasses 1/4 cup apple cider vinegar 1/4 cup water 1 tbsp Worcestershire sauce 2 1/2 tsp dry mustard 2 tsp paprika 1/2 tsp garlic powder 1/4-1/2 tsp cayenne pepper (this is optional - I leave it out) 1 1/2 tsp salt 1 tsp pepper 1/8 cold water mixed with 1 tbsp corn starch (optional - I do add this because I like my sauce thick) Combine all the ingredients in a sauce pan except for the final cold water/cornstarch mixture. Bring to a boil, then turn the heat down to a simmer for five minutes so that the sugar is dissolved. If you like a thicker sauce ( like me) add the cornstarch slurry. Simmer while it thickens, but watch it carefully as it will thicken very fast. Store in a sealed jar in the fridge.
