Ingredients

Directions

Make the soup

  1. Place the vegetable soup in a saucepan with hot water underneath and simmer for 10 minutes.

  2. Add the turtle, salt, cayenne pepper, allspice, and the yolks of the hard-boiled eggs, mash them smooth, and boil for a few minutes.

  3. Cream the butter and flour together, then stir into the soup until it thickens.

Finish and serve

  1. Warm the Madeira wine and pour it into the soup just before serving.

  2. Serve with thin slices of lemon, removing the seeds, in each bowl.

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

What each ingredient does

Turtle
Provides the main meat and body of the soup.
Hard-boiled eggs
Their mashed yolks thicken the soup and add richness.
Madeira wine
Adds a sweet, aromatic depth poured in just before serving.
Butter
Adds fat and richness, and helps carry flavour in the thickened soup.
Browned flour
Thickens the soup when creamed with butter and stirred in.

The step that matters

Stirring in the butter and flour mixture. Flour must be fully blended with butter before it hits the hot soup, otherwise it clumps instead of thickening evenly. Keep the soup simmering while stirring so the starch swells and sets smoothly.

Swap the allspice

How well each one fits the dish's main ingredients (egg, madeira wine, pepper, butter, flour):

  1. Nutmegfits better
  2. Parsleyfits better
  3. Thymefits better
  4. Allspicethe original

Fit is the average pairing score against egg, madeira wine, pepper, butter, flour. Candidates are from the same food group and used in at least 100 recipes.
