A Quickly Made Turnip Soup

Ingredients

Directions

Make the soup

  2. Optionally, add sliced onion while stewing.

  3. Stew gently for 25 to 30 minutes until the turnips are soft.

  4. Rub the mixture through a sieve to create a smooth pulp.

  5. Add another quart of stock, sugar, salt, and white pepper.

  6. Bring to a boil for 2 to 3 minutes, skimming off any foam.

Serve

  1. Serve hot.

  2. Optionally, add a little cream for improved color.

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

What each ingredient does

Turnips
Provide the main body and flavor of the soup once cooked and puréed.
Stock
Supplies the liquid that cooks the turnips and gives the soup its savoury base.
Cream
Adds richness and a paler, creamier color to the finished soup.

The step that matters

Rubbing the stewed mixture through a sieve. Soft, well-cooked turnips are needed to pass through the sieve smoothly. Undercooked pieces will stay grainy, leaving the pulp rough instead of smooth.

Swap the onion

The recipe marks onion as optional. How well each one fits the dish's main ingredients (turnip, veal, sugar, white pepper, cream):

  1. Leekfits better
  2. Arrowrootfits better
  3. Parsnipfits better
  4. Onionthe original

Fit is the average pairing score against turnip, veal, sugar, white pepper, cream. Candidates are from the same food group and used in at least 100 recipes.
