Pease Soup

Ingredients

Directions

Prepare

  1. Rinse the split peas and combine them with 3 quarts of cold soft water in a large pot.

  2. Add the bacon, roast beef bones, or anchovies to the pot.

  3. Wash and cut the celery, then add it along with the peeled onions and herbs.

Simmer and strain

  1. Simmer gently over low heat for about 3 hours, stirring every 15 minutes to prevent sticking.

  2. Optionally, fry sliced celery and onions in butter until lightly browned, then add to the soup.

  3. Strain the soup through a coarse sieve, then through a fine sieve or tamis.

  4. Return the strained soup to the pot, add black pepper, and boil for another 10 minutes.

  5. Skim off any fat that rises to the surface.

Finish

  1. In a frying pan, heat the drippings or lard and fry the toasted bread pieces until golden.

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

What each ingredient does

Split peas
Break down during long simmering to thicken the soup body.
Bacon
Adds savory, smoky flavor and fat to the broth.
Celery
Contributes aromatic flavor that builds the soup's base taste.
Onions
Add sweetness and aromatic depth as they cook down.
Drippings or lard
Fry the bread, adding richness and browning to the croutons.

The step that matters

Stirring during the long simmer. Split peas are starchy and settle on the bottom of the pot, where they scorch easily. Regular stirring keeps them from sticking and burning, which would give the soup a bitter, burnt taste.

Swap the peas

How well each one fits the dish's main ingredients (beef, celery, onion, marjoram, pepper, bread):

  1. Beansfits better
  2. Lentilsfits better
  3. Chestnutfits better
  4. Peasthe original

Fit is the average pairing score against beef, celery, onion, marjoram, pepper, bread. Candidates are from the same food group and used in at least 100 recipes.
