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

What each ingredient does

Asparagus
Forms the main vegetable layer and provides the tender texture of the topping.
Butter
Adds richness and helps the toast brown and taste savoury.
Flour
Thickens the butter and liquor mixture into a light sauce.
Liquor (such as white wine)
Adds acidity and moisture to the sauce poured over the asparagus.

The step that matters

Stir the butter and flour mixture into the liquor. Stirring the butter and flour into the liquor helps the flour disperse evenly, so the sauce thickens smoothly instead of forming lumps.

Swap the asparagus

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

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

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