Ketchup + Shallot
A good pairing. Cooks put them together in 476 recipes, and they share 32 flavor molecules: the top 16% of all ingredient pairs. We hold little distinguishing chemistry for one of them, so the recipe count carries this verdict.
Do ketchup and shallot go together?
Yes. 476 recipes in our collection combine them, and they share 32 flavor molecules. That places them in the top 16% of every ingredient pair we score.
Read this with the evidence note above in mind.
Why they work
More than half of ketchup's flavor molecules (32 of 45) also occur in shallot. Among the shared key aromas are ethanol (alcoholic, ethereal) and decanoic acid (soapy, waxy). Most of what they share is background chemistry many foods carry, so the overlap does little for the smell.
What each one brings
ketchup
The tartness. Sour notes make up 35% of its labelled aroma molecules, against 14% for shallot. It carries 13 molecules shallot doesn't have.
shallot
The fresh, green side. Green notes make up 12% of its labelled aroma molecules, against 0% for ketchup. It carries 191 molecules ketchup doesn't have.
Add a third ingredient
- Sauce: the best fit for both, top 1% of pairs with ketchup, top 14% with shallot.
- Capers: top 17% of pairs with ketchup, top 1% with shallot.
- Whiting: top 1% of pairs with ketchup, top 17% with shallot.

Recipes with ketchup and shallot
We have no browsable recipe that lists both ketchup and shallot.
Can you swap one for the other?
Only partly. Most of ketchup's flavor molecules (32 of 45) are also found in shallot, but shallot has 191 that ketchup lacks. Ketchup gives you part of shallot'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.
