Why it works: Cucumber and onion match in chemistry and in kitchens. They rank in the top 8% of all ingredient pairs, and cooks put them together in 6,050 recipes. Both carry 2-isopropyl-3-methoxypyrazine, which smells earthy, pea. The science ↓
Cucumbers with Eggs
Ingredients
Directions
Prepare the cucumbers
Pare, quarter, and cut the cucumbers into dice-sized squares.
Boil the cucumbers in water, then transfer them to a stewpan.
Make the sauce
Add the onion, ham, butter, and salt to the stewpan.
Cover and cook on low heat for 15 minutes, stirring often to prevent burning.
Dredge in flour and add enough veal stock to just cover the cucumbers.
Stir well and maintain gentle heat until no scum rises.
Remove the ham and onion, then stir in the beaten egg yolks and cream.
Finish and serve
Remove from heat and add lemon juice just before serving.
Top with poached eggs before serving.

Butter and flour barely smell alike, yet cooks put them together in 124,287 recipes: they work on texture and structure more than aroma.
Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Cucumbers
- Form the bulk of the dish and release moisture that becomes part of the sauce.
- Butter
- Adds richness and fat, carrying flavour and giving the sauce a smooth mouthfeel.
- Flour
- Thickens the cooking liquid into a body-rich sauce that clings to the cucumbers.
- Egg yolks
- Enrich and thicken the sauce when stirred in gently, adding richness and colour.
- Cream
- Adds fat and smoothness, softening the sauce and mellowing its texture.
- Poached eggs
- Provide a soft, rich topping that adds protein-based body and contrast to the dish.
The step that matters
Stir in the egg yolks and cream off the heat or at gentle heat. Egg yolks thicken by gentle coagulation and curdle or turn grainy if they get too hot. Keeping the sauce at a low, steady heat lets it thicken smoothly.
Swap the clove
How well each one fits the dish's main ingredients (cucumber, onion, ham, butter, flour, veal, egg):
- Capersfits better
- Parsleyfits better
- Tarragonfits better
- Clovethe original
Fit is the average pairing score against cucumber, onion, ham, butter, flour, veal, egg. Candidates are from the same food group and used in at least 100 recipes.
