Noodle Soup

Ingredients

Directions

Make the broth

  1. Place the soup bone in a pot with cold water.

  2. Bring to a boil, then add salt and pepper.

  3. Boil for several hours.

Make the noodles

  1. To make the noodles, beat the eggs until light.

  2. Add enough flour to form a very stiff dough.

  3. Roll the dough very thin and let it dry.

  4. Roll it up tightly like a sheet of music and cut into very thin rings.

Finish and serve

  1. About 15 minutes before serving, add the noodles.

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

What each ingredient does

Soup bone
Releases collagen and flavour into the water as it simmers, giving the broth body.
Eggs
Bind the flour into a dough and add richness to the noodles.
Flour
Forms the gluten structure that holds the stiff noodle dough together.

The step that matters

Roll the dough very thin and let it dry. Dough rolled thin and dried firmly holds its shape and cooks quickly in the broth. If it stays thick or damp, the noodles turn gummy and cook unevenly.
