My husband and oldest daughter are HUGE ketchup lovers, I am not. When I make them their coveted homemade ketchup, I always reserve 2 cups to make BBQ Sauce, Shhhh...don't tell them! But, you can use store bought ketchup as well. This recipe is tangy and sweet just how I like it. If you like it with" POW, right in the kisser" , than I suggest adding Cayenne pepper to taste. This recipe can be doubled (YAY!) for canning purposes and is a great 1st time project if you've ever wanted to try your hand at canning. If not, just place it right in the fridge and it will last several months. Please check out the link below if you are new to canning.

There's only 1 thing you need to strictly follow when using this recipe. Never change the ratio of vinegar to ingrediants. You can alter/lower the PH level allowing botulism to grow. For example, if you want to double this recipe for canning purposes- Use 1 full cup of Apple Cider Vinegar.
