Lobster + Ketchup
A proven pairing. Cooks put them together in 48 recipes, and they share 42 flavor molecules: the top 9% of all ingredient pairs. We hold little distinguishing chemistry for one of them, so the recipe count carries this verdict.
Do lobster and ketchup go together?
Yes. 48 recipes in our collection combine them, and they share 42 flavor molecules. That places them in the top 9% of every ingredient pair we score.
Read this with the evidence note above in mind.
Why they work
Almost everything ketchup carries, lobster has too: 42 of ketchup's 45 flavor molecules also occur in lobster. Among the shared key aromas are ethanol (alcoholic, ethereal) and decanoic acid (soapy, waxy).
What each one brings
lobster
The fresh, green side. Green notes make up 8% of its labelled aroma molecules, against 0% for ketchup. It carries 19 molecules ketchup doesn't have.
ketchup
The tartness. Sour notes make up 35% of its labelled aroma molecules, against 25% for lobster. It carries 3 molecules lobster doesn't have.
Add a third ingredient
- Sauce: the best fit for both, top 6% of pairs with lobster, top 1% with ketchup.
- Whiting: top 5% of pairs with lobster, top 1% with ketchup.
- Haddock: top 7% of pairs with lobster, top 1% with ketchup.
- Atlantic halibut: top 10% of pairs with lobster, top 1% with ketchup.

Recipes with lobster and ketchup
We have no browsable recipe that lists both lobster and ketchup.
Can you swap one for the other?
Only partly. Almost all of ketchup's flavor molecules (42 of 45) are also found in lobster, but lobster has 19 that ketchup lacks. Ketchup gives you part of lobster'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.
