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: Oyster 38, Ketchup 0 (the typical ingredient has 12).

Do oyster and ketchup 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.

Read this with the evidence note above in mind.

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

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.

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.

Add a third ingredient

Recipes with oyster and ketchup

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

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.
