Pairing

Potato + Ketchup

A cook's pairing more than a chemical one: 22 recipes use both, though they share little aroma. They rank in the top 32% of all ingredient pairs. We hold little distinguishing chemistry for one of them, so the recipe count carries this verdict.

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: Potato 193, Ketchup 0 (the typical ingredient has 12).

Do potato and ketchup go together?

Yes, in practice. 22 recipes in our collection combine them, and they share 45 flavor molecules. That places them in the top 32% of every ingredient pair we score.

Read this with the evidence note above in mind.

What they have in common

Almost everything ketchup carries, potato has too: 45 of ketchup's 45 flavor molecules also occur in potato. Among the shared key aromas are ethanol (alcoholic, ethereal) and decanoic acid (soapy, waxy). So the pairing rests more on how cooks use them than on shared aroma.

What each one brings

potato

ketchup

The tartness. Sour notes make up 35% of its labelled aroma molecules, against 15% for potato. Every molecule it carries is also in potato.

Add a third ingredient

  • Haddock: the best fit for both, top 15% of pairs with potato, top 1% with ketchup.

Ranked by the average of its two pairing scores. Only foods used in at least 100 recipes are suggested.

Recipes with potato and ketchup

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

Can you swap one for the other?

Only partly. Almost all of ketchup's flavor molecules (45 of 45) are also found in potato, but potato has 414 that ketchup lacks. Ketchup gives you part of potato'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.
