homemade ketchup, an old-world recipe

"Deeply robust with the rich-sweet flavor of concentrated tomato, this ketchup differs from the cloying sweet varieties you find in the grocery store. Allspice and cloves, traditional inclusions often omitted in most store-bought varieties, bring a level of depth that would be otherwise absent. Not a particularly quick food, this homemade ketchup is slowly ripened and aged over a period of three to five days as beneficial bacteria metabolize the food’s natural sugars, creating a condiment that is potently rich in food enzymes and probiotics. It’s a traditional process, lactofermentation, that increases the nutritional value of the foods we eat and love.
