Ketchup (tomato ketchup)

Typical ingredients and production

Commercial ketchup usually contains concentrated tomato, distilled vinegar, sugar or high-fructose sweetener, salt and seasonings such as onion, garlic, cloves, allspice and pepper. The mixture is cooked, reduced to a smooth consistency and then pasteurized to ensure shelf stability. Home recipes may substitute sweeteners, adjust spices or use fresh tomatoes for a less processed result. For more general information, see overview.

History and development

The name "ketchup" derives from a fermented fish sauce from Southeast Asia that entered European languages centuries ago and evolved in both ingredients and preparation. In Europe and North America, recipes shifted toward tomato-based versions during the 18th and 19th centuries. Over time manufacturers refined texture and flavor, and the bottled tomato ketchup we recognize today became a common pantry item.

Uses and serving ideas

Ketchup is used as a condiment, ingredient and dip. Common pairings include:

• Fried potato products such as french fries and chips.
• Sandwiches and burgers — often spread or added as a topping; see burger pairings.
• Sausages, hot dogs and other grilled meats; examples at serving suggestions.
• As a component in sauces, marinades and meatloaf glazes.

Many people also use ketchup to add a quick flavor boost to vegetables, eggs or fried foods; culinary uses are described in broader recipes at recipe resources.

Variants, distinctions and notable facts

Variants include reduced-sugar or salt formulations, spicy or flavored ketchups, and regional styles that emphasize different spice blends. Ketchup is distinct from plain tomato purée, passata or pasta sauce due to its added vinegar and sweetener and its intended role as a condiment. For information focused on the raw ingredient, see tomato details.

Nutritional and cultural notes

As a condiment, ketchup contributes flavor in small quantities but can add notable sugar and sodium to a meal. It is shelf-stable when unopened and refrigerates after opening to preserve freshness. Ketchup has become a cultural staple in many countries and remains one of the most recognizable and widely used table condiments worldwide.
