Ingredients
Directions
Make the dough
Make a hole in the flour and add the sugar, butter, milk, and yeast in that order.
Do not stir after adding the ingredients.
Arrange the mixture in the evening and set it in a cool place until the next morning.
Knead, rise and bake
Mix the ingredients together and knead for 15 minutes.
Return the dough to the cool place until it rises.
Bake for 15 minutes.

Flour and butter share little aroma chemistry, yet 124,287 recipes mention both: they likely work on texture and structure more than aroma.
Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Flour
- Provides the structure that holds the dough together and traps gas as it rises.
- Yeast
- Produces carbon dioxide as it ferments, which makes the dough rise.
- Milk
- Adds moisture and milk proteins that contribute to a soft crumb and browning.
- Butter
- Adds fat that tenderizes the crumb and gives a rich flavor.
- Sugar
- Feeds the yeast, adds sweetness, and helps the crust brown.
The step that matters
Set the dough in a cool place overnight. A slow, cool rise lets the yeast ferment gradually, developing flavor and a controlled rise. If the dough gets too warm, the yeast can overproof and weaken the structure.
“What each ingredient does” and “The step that matters” were written by Claude from this recipe’s own method and reviewed in samples by CompKitchen.
