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 350°F (175°C) in the steps was added when the recipe was transcribed, as a starting point.
Make the base
Melt the butter, add the flour, and gradually whisk in the scalded milk with salt and pepper to make a cream sauce.
Remove from heat and stir in the beaten egg yolks.
Add the cooked spinach and gently fold in the stiffly beaten egg whites.
Bake and serve
Pour the mixture into a buttered serving dish and place it in a pan of hot water.
Bake at 350°F (175°C) for 30 minutes and serve immediately.

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
- Eggs
- Egg whites trapped by folding give the soufflé its lift, and yolks enrich the set custard.
- Flour
- Thickens the butter and milk into a cream sauce that holds the spinach and eggs.
- Milk
- Forms the liquid base of the cream sauce, adding moisture and a soft texture.
- Cooked spinach
- Supplies the main flavour and moisture; it must be well drained so the soufflé does not turn watery.
- Butter
- Enriches the sauce and adds richness and flavour to the base.
The step that matters
Folding in the egg whites. Stiffly beaten whites hold air that makes the soufflé rise. Folding gently keeps that air in; stirring hard deflates the mixture and leaves it dense.

Fit is the average pairing score against milk, butter, flour, egg, pepper. Candidates are from the same food group and used in at least 100 recipes.
