  2. Drain the peas and pound them into a puree.

  3. Gradually mix the puree into the veal or beef broth.

  4. Season the broth with pepper and salt; add mace and sugar if using veal broth.

Prepare the garnishes

  1. Fry the boiled leeks and lettuce in butter until lightly browned.

  2. Fry the diced bread until golden and crispy.

  3. If in season, add boiled asparagus heads; otherwise, use hop-tops.

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

What each ingredient does

Large green peas
Form the main body of the soup when cooked and pureed, giving it thickness and flavour.
Veal or beef broth
Supplies the liquid base and savoury meaty flavour for the soup.
Butter
Browns the leeks and lettuce, adding nutty flavour and golden colour.
Slices of bread
Fried into dice, they add crisp texture contrasting with the smooth soup.

The step that matters

Pureeing the cooked peas. Peas must be fully cooked so they break down smoothly; undercooked peas stay grainy and give the soup an uneven texture.

Swap the mace

The recipe marks mace as optional. How well each one fits the dish's main ingredients (peas, parsley, sorrel, chive, veal, pepper, sugar):

  1. Tarragonfits better
  2. Capersfits better
  3. Thymefits better
  4. Macethe original

Fit is the average pairing score against peas, parsley, sorrel, chive, veal, pepper, sugar. Candidates are from the same food group and used in at least 100 recipes.
