Why it works: Milk and butter are a kitchen classic. They rank in the top 7% of all ingredient pairs, and cooks put them together in 81,283 recipes. Both carry (z)-4-heptenal, which smells biscuit, cream. The science ↓
Stewed Leeks with Plovers' Eggs
Ingredients
Directions
Prepare
Thoroughly wash the leeks and cut them into thin rings.
Boil the leeks in plenty of water until tender, then strain and discard the water.
Hard boil the plovers' eggs.
Peel the boiled eggs.
Make the sauce and serve
In a saucepan, melt the butter, add the flour, and stir to make a roux.
Gradually add the milk to the roux, stirring until thickened.
Warm the leeks in the thickened milk mixture.
Serve the peeled eggs hot with the stewed leeks.

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
- Leeks
- Form the main body of the dish, becoming soft and tender after boiling and stewing.
- Butter
- Enriches the sauce and carries flavour when melted with the flour.
- Flour
- Thickens the milk into a smooth sauce when cooked with the butter as a roux.
- Milk
- Forms the liquid base of the sauce, which thickens as it heats with the roux.
- Eggs
- Provide the protein-rich centrepiece, served hard boiled and peeled.
The step that matters
Gradually add the milk to the roux. Adding milk slowly while stirring lets the starch in the flour hydrate evenly, preventing lumps and giving a smooth, thickened sauce.
Swap the leek
How well each one fits the dish's main ingredients (egg, milk, butter, flour):

- Leekthe original
- Asparagusfits about as well
Fit is the average pairing score against egg, milk, butter, flour. Candidates are from the same food group and used in at least 100 recipes.
