Marrowball Soup

Ingredients

Directions

Make the dumplings

  1. Melt the piece of marrow slowly until slightly cooled.

  2. Add the grated bread crumbs, egg yolk, salt, and nutmeg; mix well with a little cold water.

  3. Take a teaspoonful of the mixture and drop it into boiling stock.

  4. Do not cover the kettle; if the ball falls apart, add more bread crumbs.

Cook in the stock

  1. Drop the mixture by the spoonful into the stock and let it boil slowly for three minutes.

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

What each ingredient does

Bone marrow
Melted fat that gives the dumplings richness and a moist, tender texture.
Bread crumbs
Absorb moisture and give the mixture body so the dumplings hold their shape.
Egg yolk
Binds the mixture together so it holds its shape when cooked.

The step that matters

Testing the first dumpling in the stock. If the mixture is too wet it falls apart in the hot liquid. Adding bread crumbs stiffens it so the dumplings hold together while they simmer.
