Why it works: Butter and bread are a kitchen classic. They rank in the top 7% of all ingredient pairs, and cooks put them together in 27,232 recipes. Both carry delta-decalactone, which smells sweet, creamy. The science ↓
Lettuce with Cream
Ingredients
Directions
Prepare the lettuce
Trim off the outer leaves of the lettuce and wash the heads in cold water several times.
Place the lettuce in a saucepan with boiling water and ½ teaspoon of salt; cook for 10 minutes.
Immerse the cooked lettuce in cold water, drain in a colander, and press dry.
Chop the lettuce finely.
Make the cream sauce
In a saucepan, melt the butter, then add the flour and cook until light brown.
Stir in the chopped lettuce and season with salt, pepper, and nutmeg.
Slowly add the cream and let it cook for 10 minutes.
Serve
Before serving, garnish with quartered hard-boiled eggs and toasted bread.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Lettuce
- Forms the bulk of the dish, becoming tender and soft when cooked and then chopped.
- Butter
- Enriches the sauce and carries flavor, with the melted fat coating the flour.
- All-purpose flour
- Cooked in the melted butter, it thickens the cream sauce as a roux.
- Heavy cream
- Adds richness and body, thickening the sauce into a smooth, creamy texture.
The step that matters
Cooking the flour in the butter. Cooking the flour in melted butter until light brown removes its raw starchy taste and lets it thicken the cream evenly. Adding the cream too quickly or without the roux cooking can leave lumps or a pasty flavor.
Swap the lettuce
How well each one fits the dish's main ingredients (butter, flour, pepper, nutmeg, cream, egg, bread):
- Spinachfits better
- Leekfits better
- Shallotfits better
- Lettucethe original
Fit is the average pairing score against butter, flour, pepper, nutmeg, cream, egg, bread. Candidates are from the same food group and used in at least 100 recipes.
