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 ↓
Cream of Spinach
Ingredients
Directions
The book gives no cooking times; the times in the steps were added in transcription, so check for doneness rather than trusting the clock.
Prepare
Wash and chop the spinach.
Make the sauce
In a saucepan, melt the butter over medium heat.
Add the flour and stir for 1 minute.
Gradually whisk in the milk, cooking until thickened.
Finish and serve
Add the spinach, salt, and pepper, and cook for 5 minutes.
Serve hot, topped with croutons.

The pairs that carry this dish. Each one is judged two ways: how much their aromas overlap, and how often cooks already put them together.

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 vegetable flavour and body, wilting into the sauce as it cooks.
- Butter
- Adds fat and richness, and carries flavour through the sauce.
- All-purpose flour
- Cooked with the butter to form a roux that thickens the milk into a smooth sauce.
- Milk
- Forms the liquid base of the sauce, which thickens as the starch in the flour swells.
The step that matters
Adding the milk to the roux. Milk added all at once or too quickly can form lumps. Adding it gradually while whisking keeps the flour starch dispersed so the sauce thickens smoothly.
Swap the spinach
How well each one fits the dish's main ingredients (butter, flour, milk, pepper):

- Spinachthe original
Fit is the average pairing score against butter, flour, milk, pepper. Candidates are from the same food group and used in at least 100 recipes.
“What each ingredient does” and “The step that matters” were written by Claude from this recipe’s own method and reviewed in samples by CompKitchen.
