Why This Recipe Works
At its most basic, ketchup is a simple combination of tomatoes, vinegar, salt, and spices, but most store-bought ketchup also contains high-fructose corn syrup—a red flag for paleo dieters. We wanted to create a recipe for classic ketchup without the added preservatives and refined sugars. We started out with deeply flavored tomato paste as our base, which gave us the thick texture and tomatoey backbone we wanted. Simple white vinegar provided brightness and tang. Ground mustard, onion powder, garlic powder, and just a pinch of ground allspice offered complexity, while coconut sugar gave the rich mixture some much-needed sweetness. To bring all the flavors together and achieve the perfect, spreadable consistency, we simmered the ketchup for about 10 minutes.
