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

What each ingredient does

Flour
Gluten proteins form the elastic network that gives the rolls their structure.
Yeast
Produces carbon dioxide gas that makes the dough rise and become light.
Milk
Adds moisture and softness, and its sugars help the crust brown.
Egg
Adds richness and helps bind the dough for a tender structure.
Butter
Adds fat that softens the crumb and gives a richer flavour.

The step that matters

Form the dough with minimal handling. Pressing and reshaping the risen dough knocks out the gas bubbles the yeast built and overworks the gluten, which leads to dense rolls instead of light ones.
