Ketchup
Sweet and tangy with a ripe tomato backbone, mild vinegar brightness, and a hint of warming spice.
Lens analyzedKetchup is a thick, tangy tomato-based condiment that is one of the most widely used table sauces in North American kitchens. It doubles as a cooking ingredient in glazes, meatloaf, barbecue sauces, and dipping mixtures.
Where it comes from
Ketchup's journey is a multicultural one: starting as a fermented fish sauce in Southeast Asia, travelling to Britain via traders, and then being reimagined entirely in the United States with tomatoes as the star. By the late 1800s, Heinz's bottled version was on tables from coast to coast, and the tangy, sweet profile it established became the global standard.
Varieties — Standard tomato ketchup is the dominant form, but you will also find banana ketchup (a beloved Filipino condiment with a sweeter, spiced flavor), low-sugar versions, and organic or no-HFCS options at most grocery stores.
In Filipino cuisine, banana ketchup—dyed red to mimic tomato ketchup—is the default condiment for fried foods and is used in sweet spaghetti sauce. In classic American diners, ketchup on the table is as expected as salt and pepper.
In a modern kitchen — A tablespoon of ketchup stirred into a braise or chili adds a quiet tomato sweetness and body without tasting like ketchup — it is a discreet umami booster.
Buying it
Look for ketchup with tomatoes listed first in the ingredients. Avoid bottles where high-fructose corn syrup dominates if you prefer a cleaner profile; many brands now offer cane-sugar or no-added-sugar versions. Once opened, refrigerate and use within six months.
Storing it
Refrigerate after opening and wipe the cap clean so it doesn't crust shut. It keeps well cold; discard if it darkens noticeably or smells fermented.
Keeps about 6 months in the fridge.
Out of ketchup? Good swaps
- Tomato paste + vinegar + sugar — Mix 3 tbsp tomato paste with 1 tbsp vinegar and 1 tsp sugar to approximate 3–4 tbsp ketchup in cooked dishes.
- Sriracha or chili sauce — Works as a spicier 1:1 substitute in dipping contexts where heat is welcome.
- Banana ketchup — Use 1:1 in Filipino recipes or wherever a sweeter, fruitier ketchup is the intent.
