Why it works: Lemon and pepper match in chemistry and in kitchens. They rank in the top 3% of all ingredient pairs, and cooks put them together in 27,047 recipes. Both carry trans-2-nonenal, which smells cardboard, fatty. The science ↓
Chou-de-Mer Glace a LA Creme {Cold Seakale with Cream Sauce)
Ingredients
Directions
Prepare
Trim and wash the sea kale, then soak it in water with a pinch of salt.
Cook the kale
In a stew‑pan, combine water, lemon juice, and flour mixed with a little water.
Season with salt and bring to a boil.
Tie the sea kale in bundles and cook in the boiling water until tender.
Drain the sea kale and place it on a slice of toasted bread.
Make the sauce and serve
In a stew‑pan, whisk the cream and egg yolks over low heat until hot but not boiling.
Add lemon juice and season with salt and pepper.
Pour the sauce over the sea kale and serve immediately.
Chill the cooked sea kale in ice for 2 hours and serve with a cold cream sauce mixed with mayonnaise.

Flour and egg barely smell alike, yet cooks put them together in 106,462 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
- Sea kale
- Forms the main body of the dish, with a tender texture once cooked.
- Cream
- Adds richness and a smooth, velvety body to the sauce.
- Egg yolks
- Thicken the cream sauce as they gently set over low heat.
- Flour
- Thickens the cooking liquid, giving it body.
- Lemon juice
- Adds acidity that brightens the sauce and cooking liquid.
The step that matters
Whisking the cream and egg yolks over low heat. Egg yolks scramble if overheated, so the mixture must stay below boiling and be whisked constantly. Gentle heat lets the yolks thicken the cream smoothly.
Swap the lemon

Fit is the average pairing score against flour, cream, egg, pepper, bread. Candidates are from the same food group and used in at least 100 recipes.
