Pairing

Onion + Vodka

A cook's pairing more than a chemical one: 66 recipes use both, though they share little aroma. They rank in the top 35% 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 vodka: 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: Onion 135, Vodka 0 (the typical ingredient has 12).

Do onion and vodka go together?

Yes, in practice. 66 recipes in our collection combine them, and they share 28 flavor molecules. That places them in the top 35% of every ingredient pair we score.

Read this with the evidence note above in mind.

What they have in common

Almost everything vodka carries, onion has too: 28 of vodka's 35 flavor molecules also occur in onion. 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

onion

The sulfurous side. Sulfurous notes make up 13% of its labelled aroma molecules, against 3% for vodka. It carries 337 molecules vodka doesn't have.

vodka

The tartness. Sour notes make up 33% of its labelled aroma molecules, against 15% for onion. It carries 7 molecules onion doesn't have.

Can you swap one for the other?

Only partly. Most of vodka's flavor molecules (28 of 35) are also found in onion, but onion has 337 that vodka lacks. Vodka gives you part of onion's character without most of its sulfurous side. This compares flavor only; texture, moisture and the job each does in a dish matter too.
