  2. Rub the cooked asparagus through a coarse sieve and season the pulp with coarse sea salt.

  3. Meanwhile, boil the asparagus ends for about fifteen minutes, then drain them.

Make the soup

  1. Boil the milk in a saucepan.

  2. Mix the butter and flour together, then stir into the boiling milk.

  3. Add the asparagus pulp to the milk mixture and boil for about ten minutes, stirring constantly.

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

What each ingredient does

Asparagus
Forms the main body and flavour of the soup once rubbed into a smooth pulp.
Milk
Forms the liquid base of the soup and carries the asparagus flavour.
Butter and flour
Thicken the milk slightly, giving the soup body.
Cream
Adds richness and a smooth, velvety texture to the finished soup.

The step that matters

Adding the cream without boiling. Cream can curdle or separate when boiled, and boiling also thins its texture. Adding it off the heat keeps the soup smooth and rich.

Swap the asparagus

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

  1. Potatofits better
  2. Leekfits better
  3. Arrowrootfits about as well
  4. Asparagusthe original

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