Why it works: Butter and bread are a kitchen classic. They rank in the top 7% of all ingredient pairs, and cooks put them together in 27,232 recipes. Both carry delta-decalactone, which smells sweet, creamy. The science ↓
Stewed Asparagus
Ingredients
Directions
Prepare the asparagus
Cut the asparagus into 1-inch lengths, wash, and drain.
Cook the asparagus in salted boiling water until tender.
Make the sauce
In a saucepan, melt 2 tablespoons of butter over medium heat.
Once bubbling, add 1 tablespoon of flour and mix well.
Stir in 1 cup of boiling milk, adding salt and pepper to taste.
Add the drained asparagus and a small piece of butter, stirring carefully.
Serve
Serve very hot over buttered toast.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Asparagus
- Provides the tender vegetable body and main flavor of the dish.
- Butter
- Adds richness and fat, carrying flavor through the sauce.
- All-purpose flour
- Thickens the milk into a smooth, creamy sauce when cooked with the butter.
- Milk
- Forms the liquid base of the sauce, giving it a creamy texture.
The step that matters
Adding the boiling milk to the flour and butter. Whisking the hot liquid into the butter and flour mixture is needed to avoid lumps. The starch in the flour swells as it heats, so the sauce thickens smoothly only if the roux is cooked and the milk is added and stirred steadily.
Swap the asparagus
How well each one fits the dish's main ingredients (butter, flour, milk, pepper, bread):

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