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 Souffle
Ingredients
Directions
The book gives no oven temperature. The 400°F (200°C) in the steps was added when the recipe was transcribed, as a starting point.
Prepare the spinach
Boil the spinach thoroughly.
Pass the spinach through a sieve.
Make the mixture
Add the beaten eggs and milk, then season with pepper and salt. Mix thoroughly.
Pour the mixture into well-buttered souffle dishes.
Bake
Bake at 400°F (200°C) for 10 minutes.

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 savory flavor of the souffle.
- Eggs
- Set during baking to give the souffle its structure and light, airy texture.
- Milk
- Adds moisture and softness, helping the mixture stay tender as it sets.
- Butter
- Greases the dishes so the souffle releases cleanly and browns lightly at the edges.
The step that matters
Pass the spinach through a sieve. Removing excess water and fibrous bits keeps the mixture smooth and stops it from weeping or becoming soggy as it bakes.
Swap the spinach
How well each one fits the dish's main ingredients (egg, milk, pepper, butter):
- Capsicumfits better
- Potatofits better
- Asparagusfits better
- Spinachthe original
Fit is the average pairing score against egg, milk, pepper, butter. Candidates are from the same food group and used in at least 100 recipes.
