Why it works: Flour and ketchup are a kitchen classic. They rank in the top 13% of all ingredient pairs, and cooks put them together in 2,435 recipes. Both carry ethanol, which smells alcoholic, ethereal. The science ↓

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Beefsteak
- Provides the main meat, which becomes tender through gentle stewing.
- Flour
- Coats the meat, helping it brown and lightly thickening the cooking liquid.
- Onions
- Add sweetness and savour as they soften and brown in the pan.
- Ketchup
- Adds sweetness, acidity and a tomato flavour to the finished sauce.
The step that matters
Stew gently for 30 minutes. Keeping the liquid at a gentle simmer rather than a hard boil lets the connective tissue in the beef break down slowly, so the meat turns tender instead of tough and stringy.
Swap the onion
How well each one fits the dish's main ingredients (flour, ketchup):
- Arrowrootfits better

- Onionthe original
Fit is the average pairing score against flour, ketchup. Candidates are from the same food group and used in at least 100 recipes.
