Liver + Ketchup
136 recipes in our collection mention both, and they share 9 flavor molecules, which puts them in the top 24% of random ingredient pairs. We hold little distinguishing chemistry for one of them, so the recipe count carries this verdict.
Do liver and ketchup go together?
Many recipes mention both. 136 recipes in our collection mention both, and they share 9 flavor molecules. That places them in the top 24% of a large random sample of ingredient pairs.
Read this with the evidence note above in mind.
What they have in common
They overlap on 9 flavor molecules: 20% of ketchup's 45. Among the shared key aromas is decanoic acid (soapy, waxy). Most of what they share is background chemistry many foods carry, so the overlap does little for the smell. Shared chemistry is a reason to try a pair, not a promise that it works on the plate.
Add a third ingredient
- Sauce: the best fit for both, top 23% of pairs with liver, top 1% with ketchup.
- Whiting: top 30% of pairs with liver, top 1% with ketchup.
- Haddock: top 32% of pairs with liver, top 1% with ketchup.
- Anchovy: top 12% of pairs with liver, top 2% with ketchup.
Ranked by the average of its two pairing scores. Only foods used in at least 100 recipes are suggested.
Recipes with liver and ketchup
Almost always mains: 110 of the 120 recipes with a course label are mains.
A recipe counts when its ingredient list mentions both, even as alternatives, so open a few to see how they are used. 125 of the 136 have a title we can list here.
Can you swap one for the other?
Not really. Each has a lot the other lacks: liver has 259 molecules ketchup doesn't, and ketchup has 36 that liver doesn't. Treat them as partners, not stand-ins. This compares flavor only; texture, moisture and the job each does in a dish matter too.
