  3. Remove the asparagus from the water and discard the threads.

Make the sauce

  1. In a double boiler, heat 1 pint of milk.

  2. In a separate bowl, mix 1 tablespoon of flour with 1 tablespoon of butter until smooth, then stir into the hot milk.

  3. Season the sauce with salt and pepper.

Assemble and serve

  2. Pour the sauce over the asparagus and toast.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs

What each ingredient does

Asparagus
The main vegetable, cooked until tender and served over the toast.
Milk
Forms the liquid base of the sauce, giving it body and a creamy texture.
Flour
Thickens the milk into a smooth sauce as it heats.
Butter
Adds richness and flavour to the sauce and helps blend the flour smoothly.
Bread
Provides the crisp, toasted base that the asparagus and sauce rest on.

The step that matters

Mixing the flour and butter into the hot milk. Adding the flour and butter paste to hot milk without first smoothing it can leave lumps. Mixing them into a smooth paste first lets the starch disperse evenly, so the sauce thickens smoothly as it heats.

Swap the asparagus

How well each one fits the dish's main ingredients (bread, milk, flour, butter, pepper):

  1. Capsicumfits about as well
  2. Potatofits about as well
  3. Shallotfits about as well
  4. Asparagusthe original

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