Why it works: Lemon and coriander match in chemistry and in kitchens. They rank in the top 1% of all ingredient pairs, and cooks put them together in 2,498 recipes. Both carry beta-phellandrene, which smells minty, terpene. The science ↓
Milk Soups , As Made At Paris
Ingredients
Directions
Prepare the milk
Boil the milk with salt and sugar.
Place French bread slices at the bottom of a serving dish.
Pour a little milk over the bread to moisten it and keep it warm without boiling.
Make the custard
Beat the egg yolks in the remaining milk.
Heat the milk mixture, stirring continuously until it thickens, then remove from heat immediately to prevent curdling.
Serve
For a superior soup, boil lemon peel, coriander seeds, cinnamon, and salt in milk, then strain and mix with the egg yolks before serving over the bread.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Milk
- Forms the liquid base of the soup and the custard.
- Egg yolks
- Thicken the milk into a custard as they heat, adding richness.
- French bread slices
- Soak up the warm milk to form the soft base of the dish.
- Loaf sugar
- Adds sweetness to the milk.
The step that matters
Heating the milk and yolks. Egg yolks thicken when heated gently, but if the mixture gets too hot it can scramble or curdle. Stirring constantly and removing it from heat as soon as it thickens keeps the custard smooth.
Swap the lemon
The recipe marks lemon as optional. How well each one fits the dish's main ingredients (milk, sugar, bread, egg, coriander, cinnamon):
- Vanillafits about as well
- Lemonthe original
- Figfits about as well
- Raisinfits less well
Fit is the average pairing score against milk, sugar, bread, egg, coriander, cinnamon. Candidates are from the same food group and used in at least 100 recipes.
