Why it works: Pepper and lemon 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
Scrape, wash, and scald the carrots.
Cut the carrots into slices.
Boil the carrots in hot water with a lump of butter until cooked.
Drain the carrots.
In a pan, blend butter and flour with pepper and coarse sea salt.
Add white stock and 2 egg yolks, then a squeeze of lemon.
Toss the carrots in the mixture without boiling, and serve.

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
Swap the carrot
How well each one fits the dish's main ingredients (butter, flour, pepper, egg, lemon):
- Shallotfits better
- Asparagusfits better
- Spinachfits better
- Carrotthe original
Fit is the average pairing score against butter, flour, pepper, egg, lemon. Candidates are from the same food group and used in at least 100 recipes.
