Why it works: Milk and butter are a kitchen classic. They rank in the top 7% of all ingredient pairs, and cooks put them together in 81,283 recipes. Both carry (z)-4-heptenal, which smells biscuit, cream. The science ↓
Artichoke Soup
Ingredients
Directions
Prepare the artichokes
Peel the artichokes and place them in cold water to prevent discoloration.
Grease the bottom of the saucepan with butter to prevent burning.
Boil the artichokes in minimal water until tender and they become a pulp.
Pass the cooked artichokes through a wire sieve.
Make the soup
In a separate pot, boil the milk with bay leaves.
Combine the sieved artichokes with the milk, adding sugar, white pepper, and salt to taste.
For a richer soup, add ½ cup of cream or 2 beaten egg yolks, ensuring the soup is hot but not boiling when adding the yolks.
Serve
Serve the soup with fried or toasted bread.

Milk and sugar barely smell alike, yet cooks put them together in 77,875 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
- Jerusalem artichokes
- Provide the main body and starchy pulp that thickens the soup when cooked and sieved.
- Milk
- Adds creaminess and a smooth, mellow body to the soup.
- Egg yolks (in the method)
- Enrich and thicken the soup when added gently to hot liquid, as an optional addition.
The step that matters
Adding the egg yolks. If the soup boils when the beaten yolks go in, the egg proteins scramble and the soup turns grainy. Keeping it hot but below boiling lets the yolks thicken it smoothly.
Swap the white pepper
How well each one fits the dish's main ingredients (jerusalem artichoke, milk, sugar, butter):
- Cinnamonfits better
- Nutmegfits better
- Capersfits better
- White pepperthe original
Fit is the average pairing score against jerusalem artichoke, milk, sugar, butter. Candidates are from the same food group and used in at least 100 recipes.
