Why it works: Spinach and pepper are a kitchen classic. They rank in the top 6% of all ingredient pairs, and cooks put them together in 3,400 recipes. Both carry nonanal, which smells fat, citrus. The science ↓
Spinach Soup
Ingredients
Directions
Prepare the spinach
Wash the spinach in several waters and carefully pick it.
Chop the spinach coarsely and mix it.
Cook the soup
Melt butter in a saucepan over low heat.
Add the chopped spinach and sprinkle with salt and pepper.
Stir with a wooden spoon, taking care not to let it burn.
Pour in the meat stock and let it simmer for 20 to 30 minutes.
If desired, add butter just before finishing.
Finish and serve
Place thin slices of bread in a tureen.
Pour the boiling soup over the bread.
In a bowl, beat the egg yolks and cream together.
When the soup has stopped boiling, stir in the egg and cream mixture.
Let it sit for 5 minutes off the heat.
Serve hot.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Egg yolks
- Enrich the soup and thicken it slightly when gently heated with cream.
- Cream
- Adds richness and a smooth texture to the soup.
- Spinach
- Provides the main flavour and green colour of the soup.
- Meat stock
- Forms the liquid base that carries the flavour of the soup.
- Bread
- Soaks up the broth, giving body and a softer texture.
The step that matters
Stir in the egg and cream mixture off the boil. Egg yolks scramble if the soup is boiling when they are added, leaving grainy specks. Once the soup has stopped boiling, the yolks thicken it gently and smoothly.
