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: Buttermilk 3, Ketchup 0 (the typical ingredient has 12).

Do buttermilk and ketchup go together?

Unclear. One recipe in our collection uses both, and they share 42 flavor molecules. That places them in the top 12% of every ingredient pair we score.

Read this with the evidence note above in mind.

Why they work

Almost everything ketchup carries, buttermilk has too: 42 of ketchup's 45 flavor molecules also occur in buttermilk. Among the shared key aromas are ethanol (alcoholic, ethereal) and decanoic acid (soapy, waxy).

What each one brings

buttermilk

The sulfurous side. Sulfurous notes make up 6% of its labelled aroma molecules, against 2% for ketchup. It carries 10 molecules ketchup doesn't have.

ketchup

The herbal side. Herbal notes make up 5% of its labelled aroma molecules, against 0% for buttermilk. It carries 3 molecules buttermilk doesn't have.

Add a third ingredient

  • Sauce: the best fit for both, top 2% of pairs with buttermilk, top 1% with ketchup.
  • Haddock: top 7% of pairs with buttermilk, top 1% with ketchup.
  • Atlantic halibut: top 6% of pairs with buttermilk, 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 buttermilk and ketchup

We have no browsable recipe that lists both buttermilk and ketchup. With this much shared aroma, it is the kind of novel pairing worth testing.

Can you swap one for the other?

Fairly well, for flavor. Each carries most of the other's flavor molecules (81% of buttermilk's and 93% of ketchup's are shared). This compares flavor only; texture, moisture and the job each does in a dish matter too.
