Butter and flour barely smell alike, yet cooks put them together in 124,287 recipes: they 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
- Forms the gluten network that gives the rolls their structure and chew.
- Yeast
- Produces gas as it ferments, which leavens the dough so it rises.
- Egg whites
- Trap air when beaten, adding lightness and helping the rolls hold their shape.
- Butter
- Adds fat that tenderises the crumb and gives a richer flavour.
- Milk
- Adds moisture and softness to the dough and helps browning in the oven.
- Sugar
- Adds sweetness and feeds the yeast, and helps the crust brown.
The step that matters
Folding in the beaten egg whites. Stiff beaten egg whites hold air that lifts the dough. Stirring them in too vigorously collapses the foam, so the rolls lose lightness and rise less in the oven.
“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.
