Why it works: Leek and turnip match in chemistry and in kitchens. They rank in the top 1% of all ingredient pairs, and cooks put them together in 1,046 recipes. Both carry coumarin, which smells sweet, hay. The science ↓
Leeks with Poached Eggs
Ingredients
Directions
Prepare
Slice the onion, carrot, and turnip thinly. Prepare the leeks by removing the roots and dark green parts, then soak in cold water.
Bring the leeks to a boil in the water, then strain.
Cook the leeks
In a stewpan, heat 2 tablespoons of butter, add the leeks, onion, carrot, turnip, bouquet garni, bay leaf, and mace. Fry slowly for 15 minutes.
Add the stock, cover, and cook gently for about 1.5 hours.
Cut the leeks lengthwise into quarters and then into 2 or 3 pieces. Keep them warm.
Make the sauce and serve
In another pan, melt the remaining butter, add the flour, and fry for a few minutes. Gradually stir in the milk and bring to a boil.
Strain any remaining stock into the sauce.
Arrange the toast in the center of a serving dish, pile the leeks on top, pour the sauce over, and place the poached eggs around the dish.

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 tender and sweet during long, gentle cooking.
- Butter
- Carries the aromatics during slow frying and enriches the flavor of the sauce.
- Flour
- Thickens the milk and stock into a smooth, cohesive white sauce.
- Milk
- Forms the body of the white sauce, adding creaminess and mild richness.
- White stock
- Moistens and slowly braises the leeks, and its remainder enriches the sauce.
- Eggs
- Provide a soft, runny yolk that enriches the leeks and sauce when broken.
The step that matters
Fry the flour in butter before adding milk. Cooking the flour in butter for a few minutes cooks out its raw starch taste and lets it thicken evenly, so the sauce is smooth rather than lumpy or floury.
Swap the mace
How well each one fits the dish's main ingredients (leek, onion, carrot, turnip, butter, flour, milk):
- Parsleyfits better
- Capersfits better
- Thymefits better
- Macethe original
Fit is the average pairing score against leek, onion, carrot, turnip, butter, flour, milk. Candidates are from the same food group and used in at least 100 recipes.
