Spring Vegetable Soup

Ingredients

Directions

Prepare the meat

  1. Cut the meat from the bones of the shin of beef and knuckle of veal using a sharp knife.

  2. Remove all fat from the meat and set it aside for other uses.

  3. Break the bones in half and extract the marrow, setting it aside as well.

  4. Place the meat and bones in a large stockpot or stewpan.

Simmer the broth

  1. Add 5 pints of cold water and 1 teaspoon of coarse sea salt to the pot.

  2. Cover the pot and bring it to a boil quickly.

  3. Skim off any scum that rises to the surface with a spoon.

  4. Reduce the heat and let the soup simmer gently for 5 hours.

Add the vegetables

  1. Scrape and slice the young carrots.

  2. Peel and slice the young turnip.

  3. Wash the leek and celery, then cut them into squares.

  4. Wash the cauliflower and add it to the pot along with the peas.

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

What each ingredient does

Shin of beef
Long simmering breaks down its connective tissue, giving the broth body and tender meat.
Knuckle of veal
Bones and connective tissue release gelatin, adding body and richness to the broth.
Cauliflower
Holds its shape during simmering and adds mild bulk to the soup.
Peas
Add sweetness and soft texture to the finished soup.

The step that matters

Skim off the scum after boiling. Scum is coagulated protein and impurities that rise as the liquid heats. Removing it early keeps the broth clear and clean-tasting rather than cloudy or greasy.

Swap the peas

How well each one fits the dish's main ingredients (beef, veal, carrot, turnip, leek, celery, cauliflower):

  2. Beansfits better
  3. Chestnutfits about as well
  4. Peasthe original

Fit is the average pairing score against beef, veal, carrot, turnip, leek, celery, cauliflower. Candidates are from the same food group and used in at least 100 recipes.
