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

What each ingredient does

Eggs
Bind the dough and add richness and structure to the noodles.
Flour
Provides the gluten structure that gives the noodles their body.
Butter
Adds fat for tenderness and flavor in the dough.
Sour milk
Its acidity reacts with the baking soda and adds tang to the dough.
Baking soda
Reacts with the acid in the sour milk to lighten the dough.

The step that matters

Stir the strips slowly into boiling broth. Dough strips added to boiling liquid can clump together or break apart if stirred roughly. Gentle stirring keeps them separate and lets them cook evenly through.
