Notes
Ketchup will keep for up to 2 weeks in the fridge White vinegar can be used in lieu of apple cider vinegar, but it will have more of a tang, this can be balanced with added sugar. If you prefer a spicy ketchup add in more spices. This is a small batch yield. If you have a larger family or just really love ketchup, double this recipe.
