Calf's Foot Broth

Ingredients

Directions

Make the broth

  1. Place the cleaned calf's foot in a saucepan with water, lemon rind, sugar, and salt.

  2. If using, add the knuckle-bone of ham.

  3. Simmer gently until the liquid is reduced by half, skimming occasionally.

Finish and thicken

  1. Pour out the broth and let it cool to remove the fat.

  2. Return the broth to the saucepan, bring to a boil, and add the beaten egg yolks.

  3. Stir over heat for a few minutes until thickened, but do not let it boil.

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

What each ingredient does

Calf's foot
Releases gelatin into the water, giving the broth body and a silky, gelling texture.
Egg yolks
Thicken the broth as they heat, adding richness and a smooth, velvety body.
Ham knuckle-bone
Adds savoury, meaty depth to the broth's flavour.

The step that matters

Stirring in the egg yolks. Egg yolks thicken through gentle heat; if the broth boils, the proteins scramble and curdle, leaving a grainy texture instead of a smooth, thickened broth.

Swap the lemon

How well each one fits the dish's main ingredients (sugar, ham, egg):

  1. Vanillafits about as well
  2. Lemonthe original
  3. Figfits about as well
  4. Applefits about as well

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