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 ↓
Cream of Spinach
Ingredients
Directions
Prepare the spinach
Boil the spinach until tender.
Strain the spinach and reserve the cooking liquid.
Make the soup
In a saucepan, melt the butter and mix in the flour to form a roux.
Gradually add the reserved cooking liquid and stock, stirring until smooth.
Stir in the cream or milk.
Just before serving, add the beaten egg and cook for 1 minute.

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
What each ingredient does
- Spinach
- Provides the main body, color, and earthy flavor of the soup.
- Butter
- Carries flavor and, with the flour, forms the roux that thickens the soup.
- Flour
- Thickens the liquid when cooked with butter into a roux.
- Cream or milk
- Adds richness and a smooth, creamy texture.
- Egg
- Adds richness and helps thicken the soup when gently cooked.
The step that matters
Adding the beaten egg. Egg proteins set with heat, so if the soup is too hot or boils after the egg goes in, it can curdle and turn grainy. Add it just before serving and keep the heat low.
Swap the spinach
How well each one fits the dish's main ingredients (butter, flour, cream, egg):
- Leekfits better
- Chivefits about as well
- Asparagusfits about as well
- Spinachthe original
Fit is the average pairing score against butter, flour, cream, egg. Candidates are from the same food group and used in at least 100 recipes.
