Vinegar is a vegetable and it contains no blood, nor animal fat. It is possible to make your ketchup vegan! Just add an extra step when you cook your sauce; use water instead of the tomato’s juice and don’t use any type of vinegar. But it will be hard to find one because all kind of sauces have vinegar as main ingredient (although apple cider vinagrette can be vegan-friendly). Some ketchup brands are already vegan friendly and in some countries it has been approved by Food Standards authorities as non-animal products.
