Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Flour
- Forms the structure of the dough that holds everything together.
- Butter
- Adds fat that makes the dough tender and smooth to work with.
- Egg
- Binds the mixture and adds richness and moisture to the dough.
- Sugar
- Adds sweetness and helps give the dough a fine, smooth texture.
The step that matters
Knead until smooth. Kneading develops the gluten in the flour, giving the dough elasticity so it rolls without tearing. Stopping too early leaves it crumbly, while the fat and sugar keep it from toughening too much.
“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.
