-cup catsup

Catsup (also spelled ketchup) is a condiment made from tomatoes, vinegar, sugar, and spices, originating in 17th-century China as a fermented fish sauce called ke-tsiap before being adapted by British traders and eventually transformed into the tomato-based condiment popularized in America. The standard American formulation consists of tomato solids or tomato paste combined with vinegar (typically distilled white vinegar), sweeteners (sugar or high fructose corn syrup), salt, and spices such as garlic, onion, allspice, cloves, and cinnamon. The texture is a thick, smooth paste with a balanced sweet-sour-savory flavor profile, though regional and brand variations exist in spice ratios and sweetness levels. Commercial catsup undergoes thermal processing and often contains preservatives; home versions may vary in consistency and ingredient selection.

Catsup functions as a universal condiment and ingredient across numerous cuisines, most notably in American, British, and Canadian cooking. It is served alongside hamburgers, hot dogs, french fries, and other fried foods as a table condiment, and is incorporated into marinades, glazes, sauces, and dressings for meats and vegetables. In cooking, catsup acts as both a thickening agent and flavor base—contributing acidity, umami, and sweetness—in dishes ranging from meatloaf and baked beans to Bloody Mary cocktails and barbecue sauces. It pairs well with grilled or fried proteins and starchy sides.
