Why it works: Butter and cream are a kitchen classic. They rank in the top 8% of all ingredient pairs, and cooks put them together in 41,516 recipes. Both carry delta-dodecalactone, which smells sweet, creamy. The science ↓
Two Salsify Soups
Ingredients
Directions
Scrape 10 or 12 roots of salsify, throwing each one at a time into cold water. Then cut into very thin slices, and cover with a quart of cold water, add 1 bay leaf and 1 slice of onion, cover and cook for thirty minutes.
Add 1 pint of milk and 1 tablespoon of butter rubbed with 1 tablespoon of flour; stir carefully until boiling; add 1 level teaspoon of salt and 1 saltspoon of white pepper.
Beat the yolks of 1 or 2 eggs with a cup of cream and add at the last moment.
(Optional) Press the salsify through a sieve, or grate it before cooking.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Salsify
- Forms the main body of the soup and gives its flavour.
- Eggs
- Yolks enrich the soup and thicken it slightly when added at the end.
- Cream
- Adds richness and a smooth, silky mouthfeel.
- Butter
- Adds fat and richness, and with flour helps thicken the soup.
- Flour (in the method)
- Thickens the soup when cooked with butter into a roux.
The step that matters
Adding the egg and cream mixture. Egg yolks can curdle if they get too hot. Add them off the heat or at the last moment, and stir gently, so the soup stays smooth and thick.
Swap the white pepper
How well each one fits the dish's main ingredients (onion, butter, cream, egg):
- Nutmegfits better
- Garlicfits better
- Capersfits better
- White pepperthe original
Fit is the average pairing score against onion, butter, cream, egg. Candidates are from the same food group and used in at least 100 recipes.
