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 ↓
Carrots a LA Poulette
Ingredients
Directions
Prepare the carrots
Cover the carrots with boiling water and let them stand for five minutes.
Drain the carrots.
Cook them in a small quantity of boiling salted water until soft.
Drain again.
Make the sauce
In a saucepan, melt 3 tablespoons of butter.
Add 3 tablespoons of flour.
Stir constantly while gradually pouring in 1 cup of white stock and ½ cup of cream.
Add the cooked carrots.
Add ½ teaspoon of lemon juice.
Season with salt and pepper.
Once thoroughly heated, stir in the slightly beaten egg yolks.

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
- Butter
- Melts with the flour to form a roux that thickens the sauce and adds richness.
- All-purpose flour
- Thickens the butter and stock mixture into a smooth, cohesive sauce.
- White stock
- Forms the liquid base of the sauce and adds savory flavor.
- Cream
- Adds richness and a silky texture to the sauce.
- Eggs
- Egg yolks enrich and thicken the sauce when stirred in while heated.
The step that matters
Stir in the egg yolks once the sauce is thoroughly heated. Egg yolks thicken by gentle heat, but if the sauce boils after they are added they can scramble and turn grainy. Keep the heat moderate and stir constantly.
Swap the carrot
How well each one fits the dish's main ingredients (butter, flour, cream, lemon, egg, pepper):
- Spinachfits better
- Asparagusfits better
- Leekfits better
- Carrotthe original
Fit is the average pairing score against butter, flour, cream, lemon, egg, pepper. Candidates are from the same food group and used in at least 100 recipes.
