Potage Aux Aspekges, or Asparagus Soup

Ingredients

Directions

Prepare the vegetables

  1. Scrape and cut the asparagus into pieces and place them in a basin of clear water.

  2. In boiling water, add the lettuces, green onions, carrot, parsley, and peas with salt; boil briefly and skim.

  3. Transfer the vegetables to a fine sieve to drain.

Make the soup

  1. In a large clean saucepan, melt the butter and add the drained vegetables; stir until completely mashed.

  2. Gradually add the beef consommé while stirring gently.

  3. Once well combined, add the sugar and a little more salt, then strain through a fine sieve.

  4. Mix in the beef stock and bring to a boil; cook for 1.5 hours before serving.

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

What each ingredient does

Asparagus
Gives the soup its main flavour and tender pieces of vegetable texture.
Butter
Adds richness and carries flavour as the vegetables are mashed into the base.
Beef stock
Provides the main liquid and savoury body of the soup.
Beef consommé
Adds concentrated beef flavour and a clearer, more savoury character to the soup.
Peas
Contribute sweetness and soft body when cooked and mashed into the base.
Cabbage lettuces
Add bulk and mild vegetal body that thickens the soup when mashed.

The step that matters

Straining through a fine sieve after mashing. Mashed vegetables contain fibres and solids that stay cloudy unless fully strained. Pressing and sieving removes them, giving a smooth, even texture in the finished soup.

Swap the peas
