Scald the milk.
Let the milk cool overnight.
Make a hole in the flour and pour in the milk, yeast, cold water, sugar, and salt.
Let the mixture stand overnight.
Shape and rise
Mold the dough as for bread.

Let the rolls rise again.
Bake
Bake at 400°F (200°C).

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Flour
- Provides the gluten network that gives the rolls their structure.
- Butter
- Coats the flour particles, tenderizing the crumb and adding richness.
- Milk
- Adds moisture and milk sugars that help the crust brown.
- Yeast
- Produces carbon dioxide gas, which makes the dough rise and become light.
- Sugar
- Feeds the yeast, adds gentle sweetness, and helps browning.
The step that matters
Letting the yeast mixture stand overnight. The long slow fermentation builds flavor and gas, but the dough can over-ferment and lose its rise if the yeast runs out of food or the mixture gets too warm. Keep it cool and covered.
