check to make sure it has no sugar
apple cider vinegar
Heat the tomato paste, apple cider vinegar and apple juice in a small saucepan over medium heat.
Stir and allow to come to a simmer but not boil.
Add garlic powder and salt and cook, stirring frequently to prevent scorching.
Continue cooking until the ketchup thickens enough to evenly coat the back of a spoon.
Remove from heat and allow to cool.
