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, Sugar 14 (the typical ingredient has 12).

Do ketchup and sugar go together?

Yes. 260 recipes in our collection combine them, and they share 43 flavor molecules. That places them in the top 8% of every ingredient pair we score.

Read this with the evidence note above in mind.

Why they work

Almost everything ketchup carries, sugar has too: 43 of ketchup's 45 flavor molecules also occur in sugar. 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 24% for sugar. It carries 2 molecules sugar doesn't have.

sugar

The caramel side. Caramel notes make up 6% of its labelled aroma molecules, against 0% for ketchup. It carries 22 molecules ketchup doesn't have.

Add a third ingredient

  • Sauce: the best fit for both, top 1% of pairs with ketchup, top 13% with sugar.
  • Haddock: top 1% of pairs with ketchup, top 16% with sugar.
  • Atlantic halibut: top 1% of pairs with ketchup, top 15% with sugar.
  • Whiting: top 1% of pairs with ketchup, top 17% with sugar.

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

Recipes with ketchup and sugar

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

Can you swap one for the other?

Only partly. Almost all of ketchup's flavor molecules (43 of 45) are also found in sugar, but sugar has 22 that ketchup lacks. Ketchup gives you part of sugar's character without most of its caramel side. This compares flavor only; texture, moisture and the job each does in a dish matter too.
