Thin evidence for this pair. We hold no distinguishing chemistry for ketchup: every compound on it appears in more than 10% of ingredients, so this score is computed over the background every food shares. Distinguishing molecules on record: Ketchup 0, Oyster 38 (the typical ingredient has 12).

Do ketchup and oyster go together?

Yes. 318 recipes in our collection combine them, and they share 38 flavor molecules. That places them in the top 15% of every ingredient pair we score.

Why they work

Almost everything ketchup carries, oyster has too: 38 of ketchup's 45 flavor molecules also occur in oyster. Among the shared key aromas are ethanol (alcoholic, ethereal) and decanoic acid (soapy, waxy).

What each one brings

ketchup

The tartness. Sour notes make up 35% of its labelled aroma molecules, against 13% for oyster. It carries 7 molecules oyster doesn't have.

oyster

The fresh, green side. Green notes make up 24% of its labelled aroma molecules, against 0% for ketchup. It carries 69 molecules ketchup doesn't have.

Add a third ingredient

  • Sauce: the best fit for both, top 1% of pairs with ketchup, top 14% with oyster.
  • Whiting: top 1% of pairs with ketchup, top 16% with oyster.
  • Haddock: top 1% of pairs with ketchup, top 17% with oyster.
  • Atlantic halibut: top 1% of pairs with ketchup, top 21% with oyster.

Recipes with ketchup and oyster

We have no browsable recipe that lists both ketchup and oyster.

Can you swap one for the other?

Only partly. Most of ketchup's flavor molecules (38 of 45) are also found in oyster, but oyster has 69 that ketchup lacks. Ketchup gives you part of oyster's character without most of its fresh, green side. This compares flavor only; texture, moisture and the job each does in a dish matter too.
