The Ancient Origins of Ketchup
The story of ketchup begins not with tomatoes, but with fermented fish sauces produced in Asia centuries ago. Historians trace the earliest ancestor of ketchup to a sauce called kôe-chiap or ke-tsiap from the Fujian region of southern China. This pungent concoction was crafted from fermented fish, meat byproducts, and soybeans. It was used to enhance flavor, adding a salty and savory kick to a variety of dishes.
As European traders in the 17th century encountered this sauce, they were intrigued by its bold taste. The British, in particular, adopted it enthusiastically, bringing it back to Europe where the process of adaptation—and renaming—began in full force.
The Journey to the West
Once imported into Europe, ke-chiap rapidly evolved. Before the tomato joined the narrative, English versions popped up under the names catchup, catsup, and ketchup—each striving for a close approximation of the original Chinese or Malay words such as kicap, kecap, or ketjap. These words covered a range of savory sauces throughout Southeast Asia, mostly based on pickled fish or brined shellfish, often with the inclusion of herbs and spices.
The earliest written reference to “catchup” in English appeared as early as 1690. Moving through the 18th century, cooks and cookbook authors experimented broadly, recreating Asian-style ketchup with local ingredients from mushrooms to walnuts.
Ingredients and Early Recipes
If ketchup didn’t originally have tomatoes, what did it contain? Early Western versions were entirely tomato-free:
- Mushrooms: Mushroom ketchup was wildly popular in the UK during the 18th and 19th centuries. It offered savoriness akin to soy or Worcestershire sauce.
- Walnuts: Walnuts became a key ingredient in some regions, producing a thinner, brown sauce with a distinctive nutty undertone.
- Fish and Oysters: Some recipes even called for anchovies, shellfish, or other seafood as a protein base.
One 1727 English recipe created a ketchup-style sauce from anchovies, shallots, vinegar, white wine, cloves, ginger, mace, nutmeg, pepper, and lemon peel.
Only at the start of the 19th century did tomatoes find their way into ketchup recipes. Culinary innovators in America, always keen to try the new and novel, embraced the bright flavor and vivid color that tomatoes offered. The inclusion of tomatoes wasn’t just a flavor decision—it defined what most Americans now think of as ketchup.
Comparison Table: Early Ketchup Variants
| Type | Main Ingredient | Flavor Profile | Notable Region/Period |
|---|---|---|---|
| Mushroom Ketchup | Mushrooms | Earthy, umami, savory | 18th–19th century UK |
| Walnut Ketchup | Walnuts | Nutty, slightly bitter | 18th century UK |
| Fish Sauce (Ke-chiap) | Fermented fish | Salty, savory, slightly pungent | Ancient China |
| Tomato Ketchup | Tomatoes | Sweet, tangy, acidic | 19th century USA |
Ketchup or Catsup—A Matter of Spelling
The first known English-language use of the spelling “catsup” goes back to the early 18th century—and even appears in a 1730 poem by Jonathan Swift. Meanwhile, “ketchup” was also in circulation, especially after it was popularized by travel and trade literature. Both spellings were used interchangeably for over a century, referencing essentially the same condiment.
Here’s what most food historians and dictionaries agree on:
- The difference between ketchup and catsup is purely one of spelling and branding. There is no standardized difference in ingredients or taste between the two.
- The term “catsup” was more commonly used in parts of the American South and Midlands, whereas “ketchup” became more standard in the Northeast and on store shelves over time.
- Some recipes for “catsup” in the past referred to sauces of lighter or thinner consistency, but these were exceptions, not rules.
Consumers often wondered if one was spicier, sweeter, or more vinegary than the other. Marketers capitalized on this ambiguity, using the preference to build regional and generational brand loyalty.
Heinz and the Branding Shift
The rise of H.J. Heinz Company in the late 19th century was a turning point for ketchup’s naming conventions. Introduced in 1876, Heinz’s tomato-based product was initially labeled “catsup.” But in the 1880s, seeking a way to stand out from competitors, Heinz adopted the spelling “ketchup” for its labels.
- Heinz’s massive popularity meant that “ketchup” gained widespread recognition.
- Gradually, other producers followed suit, and “ketchup” soon outpaced “catsup” in American homes and markets.
- Some manufacturers, especially in the South, held on to “catsup” for decades, fostering local pride and a sense of nostalgia.
By the mid to late 20th century, “ketchup” was firmly entrenched as the mainstream term, with “catsup” surviving only as an occasional outlier or regional curiosity.
Label Showdown: Ketchup vs. Catsup
| Brand | Label (Year) | Description |
|---|---|---|
| Heinz | Catsup (1876–c.1880s) | Original Heinz tomato product labeled “catsup.” |
| Heinz | Ketchup (1880s–present) | Switch to “ketchup” for differentiation; becomes industry standard. |
| Del Monte, Hunt’s, and others | Catsup (1900s–1980s) | “Catsup” remained popular in the South and Midwest on major labels into the late 20th century. |
Regional Preferences and Modern Usage
Though “ketchup” now dominates supermarket shelves and restaurant menus, “catsup” remains part of the American culinary vocabulary. You are more likely to spot “catsup” in certain Southern and Midwestern communities or on vintage bottles in diners and antique shops.
The divide echoes other American language quirks—such as soda vs. pop—where a single product carries different names according to local tradition and historical happenstance.
- Most modern products labeled “catsup” and “ketchup” are virtually identical in ingredients and flavor profile.
- The preference for one term over the other is often passed down through families, dictated by local brands or household routine.
- “Ketchup” now enjoys status as the global default for the classic tomato condiment, while “catsup” lingers as a charming artifact of American food history.
Pop culture also played a role: During the 1980s, a government controversy over whether ketchup counted as a vegetable in school lunches (it didn’t) added to the mystique and mainstream dominance of “ketchup.”
