Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Butter
- Fat that coats the flour particles, keeping the crust short and tender.
- Flour
- Provides the structure that the rest of the dough is built on.
- Egg yolks
- Add richness and help bind the dough together.
- Powdered sugar
- Adds mild sweetness and helps the crust brown lightly.
The step that matters
Mix into a paste, adding water as needed.. Add water gradually and mix only until the dough holds together. Too much water or overworking develops gluten, which makes the pastry tough instead of short and crumbly.
“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.
