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 ↓
To Stew Cucumbers
Ingredients
Directions
Prepare the cucumbers
Pare and slice the cucumbers about the thickness of a brown piece.
Dust a little white pepper, coarse sea salt, and flour over them.
Fry the cucumbers in a little butter until golden.
Drain the cucumbers on a sieve.
Stew and serve
In a stew pan, prepare a brown sauce seasoned with ketchup, lemon juice, and white wine.
Add the cucumbers to the sauce and let them stew for 15 minutes.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Cucumbers
- Form the main body of the dish, softening into tender pieces as they stew in the sauce.
- Flour
- Dusted on the cucumbers, it helps them brown when fried and gives the coating some body.
- Butter
- Fat for frying, which browns the cucumber surfaces and adds rich flavour.
- Brown sauce
- Base liquid that the cucumbers stew in, carrying savoury depth through the dish.
- Lemon juice
- Adds acidity that brightens the rich sauce and balances its savoury flavour.
- White wine
- Adds acidity and aromatic complexity to the sauce as it simmers.
The step that matters
Frying the cucumbers until golden. Cucumbers hold a lot of water. If they are fried in too little butter or crowded in the pan, they steam instead of browning, and the coating turns soggy rather than golden.
Swap the white pepper
How well each one fits the dish's main ingredients (cucumber, flour, butter, sauce, ketchup, lemon, white wine):
- Capersfits better
- Tarragonfits better
- Parsleyfits better
- White pepperthe original
Fit is the average pairing score against cucumber, flour, butter, sauce, ketchup, lemon, white wine. Candidates are from the same food group and used in at least 100 recipes.
