Ingredients

Directions

Make the soup base

  1. Boil the meat until tender, then remove and cut into small pieces.

  2. Return the meat to the pot and season with mace, cloves, cinnamon, peppercorns, and chopped onion.

  3. Grind the spices before adding them.

  4. Brown the flour in a pan to thicken the soup.

Finish and serve

  1. Burn the sugar until caramelized, then add it to the soup along with the egg yolks and tomato ketchup.

  2. Boil all ingredients until fully cooked.

  3. Just before serving, stir in the claret or other wine.

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

What each ingredient does

Flour
Browned flour thickens the soup and adds a toasty, nutty flavour.
Egg yolks
Rubbed-fine yolks enrich the soup and help give it a smooth, thick body.
Sugar
Caramelized sugar adds sweetness and a deep, slightly bitter colour.
Tomato ketchup
Adds acidity, sweetness and savoury depth to the soup.
Claret or other wine
Adds acidity and aromatic depth when stirred in at the end.

The step that matters

Browning the flour. Flour browned slowly in a dry pan toasts evenly and thickens well. If it scorches, it turns bitter and can spoil the soup's flavour, so it needs steady heat and constant stirring.

Swap the onion

How well each one fits the dish's main ingredients (meat, mace, clove, cinnamon, flour, sugar, egg):

  1. Arrowrootfits better
  2. Shallotfits better
  3. Sweet potatofits better
  4. Onionthe original

Fit is the average pairing score against meat, mace, clove, cinnamon, flour, sugar, egg. Candidates are from the same food group and used in at least 100 recipes.
