  8. Slice the tongue.

  9. Strain the broth through a sieve.

Make the soup

  1. Melt the butter in a stewpan.

  2. Stir in the flour until smooth.

  3. If lumpy, strain the mixture.

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

What each ingredient does

Flour
Thickens the butter and broth into a smooth, body-rich soup.
Butter
Carries flavour and enriches the soup as the base of the roux.
Anchovies
Adds savoury depth that rounds out the broth's flavour.
Lemon juice or madeira wine
Adds acidity or sweetness that brightens the rich broth.
Hard-boiled eggs
Add richness and a soft, mild texture to the soup.

The step that matters

Stirring the broth into the butter-flour mixture. Adding liquid while stirring continuously keeps the roux smooth, since flour clumps when it meets liquid unevenly. Straining lumpy mixtures removes what stirring misses.

Swap the onion

How well each one fits the dish's main ingredients (veal, clove, mace, nutmeg, butter, flour, lemon):
