Rice + Ketchup
A good pairing. Cooks put them together in 146 recipes, and they share 45 flavor molecules: the top 25% of all ingredient pairs. We hold little distinguishing chemistry for one of them, so the recipe count carries this verdict.
Do rice and ketchup go together?
Yes. 146 recipes in our collection combine them, and they share 45 flavor molecules. That places them in the top 25% of every ingredient pair we score.
Read this with the evidence note above in mind.
Why they work
Almost everything ketchup carries, rice has too: 45 of ketchup's 45 flavor molecules also occur in rice. 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
rice
The fresh, green side. Green notes make up 13% of its labelled aroma molecules, against 0% for ketchup. It carries 383 molecules ketchup doesn't have.
ketchup
The tartness. Sour notes make up 35% of its labelled aroma molecules, against 16% for rice. Every molecule it carries is also in rice.
Add a third ingredient
- Sauce: the best fit for both, top 20% of pairs with rice, top 1% with ketchup.
- Haddock: top 26% of pairs with rice, top 1% with ketchup.
- Whiting: top 27% of pairs with rice, top 1% with ketchup.
- Atlantic halibut: top 27% of pairs with rice, 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 rice and ketchup
We have no browsable recipe that lists both rice and ketchup.
Can you swap one for the other?
Only partly. Almost all of ketchup's flavor molecules (45 of 45) are also found in rice, but rice has 383 that ketchup lacks. Ketchup gives you part of rice'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.
