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

What each ingredient does

Flour: Forms the main structure of the dumplings as its starch sets when cooked.
Baking powder: Releases gas in the moist dough, helping the dumplings rise and become light.
Butter: Coats flour particles when rubbed in, adding richness and a tender crumb.
Egg: Binds the dough and adds richness and structure as it sets.
Milk: Provides the liquid that hydrates the flour and keeps the dumplings moist.
