Why it works: Sauce and ketchup match in chemistry and in kitchens. They rank in the top 1% of all ingredient pairs, and cooks put them together in 1,099 recipes. Both carry ethanol, which smells alcoholic, ethereal. The science ↓
Creole Sauce
Ingredients
Directions
Make the tomato sauce by cooking the tomatoes and passing them through a sieve until thick.
Chop the onion and fry it in butter until yellow.
Add the green and red peppers, tomato sauce, ham, and season with salt and pepper.
Simmer for 30 minutes and serve hot.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Tomato sauce
- Forms the liquid base and gives the sauce its body and tomato flavour.
- Butter
- Fat that carries the onion's flavour and softens it as it fries.
- Ham or bacon
- Adds savoury, salty depth that seasons the sauce as it simmers.
- Green and red peppers
- Add fresh, slightly bitter vegetable flavour and some texture to the sauce.
The step that matters
Simmer for 30 minutes. Long simmering lets the tomato sauce thicken and the flavours blend. Too short a simmer leaves the sauce thin and the peppers raw-tasting.
Swap the onion
How well each one fits the dish's main ingredients (tomato, sauce, ketchup, pepper, celery, sugar, butter):
- Capsicumfits better
- Mustardfits better
- Carrotfits better
- Onionthe original
Fit is the average pairing score against tomato, sauce, ketchup, pepper, celery, sugar, butter. Candidates are from the same food group and used in at least 100 recipes.
