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 pastry when hydrated and worked.
Butter
Coats flour particles to keep the pastry tender and crumbly, and adds richness.
Egg yolk
Adds richness and helps bind the dough together.
Cold water
Hydrates the flour so the dough holds together without becoming tough.
Lemon juice
Adds a small amount of acidity that helps tenderize the dough.

The step that matters

Gradually pour in the cold water while kneading lightly. Adding too much water or overworking the dough develops gluten, making the pastry tough. Cold water and light handling keep the butter solid and the crust tender.

Swap the lemon
