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 with Cheese Sauce
Ingredients
Directions
Prepare the spinach
Wash the spinach thoroughly and soak in cold water for 1 hour.
Cover with boiling water, add salt, and cook for 15 minutes without a cover.
Make the cheese sauce
Melt the shortening in a saucepan, then blend in the flour, salt, and pepper.
Thicken the mixture in a double boiler with the milk.
Add the grated cheese and stir until melted.
Serve
Drain the spinach, press out excess water, and serve topped with the cheese sauce.

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.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Spinach
- Forms the bulk of the dish and provides its green, vegetable base.
- Shortening
- Fat that coats the flour and starts the sauce base, carrying flavor.
- Flour
- Thickens the milk into a smooth sauce as its starch swells with heat.
- Milk
- Liquid that forms the body of the sauce, giving it a creamy texture.
- Grated cheese
- Melts into the sauce, adding rich flavor and a smooth, stretchy body.
The step that matters
Thicken the sauce gently in a double boiler. Flour thickens milk as its starch swells with heat, but direct high heat can scorch the milk or leave lumps. A double boiler applies gentle, even heat so the sauce thickens smoothly.
Swap the spinach
How well each one fits the dish's main ingredients (flour, milk, pepper, cheese):
- Capsicumfits better
- Potatofits better
- Spinachthe original
- Mustardfits about as well
Fit is the average pairing score against flour, milk, pepper, cheese. Candidates are from the same food group and used in at least 100 recipes.
