Why it works: Flour and butter are a kitchen classic. They rank in the top 12% of all ingredient pairs, and cooks put them together in 124,287 recipes. Both carry isobutyraldehyde, which smells malty, green. The science ↓
Short Pastry
Ingredients
Directions
Combine flour, butter, and sugar in a bowl.
Rub together until the mixture resembles breadcrumbs.
Add the egg yolk (if using) and mix in enough cold water to form a very stiff dough.
Turn the dough onto a floured board, knead lightly, and roll out once only.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- All-purpose flour
- Provides the structure that the fat and water bind into a dough.
- Butter or beef dripping
- Coats flour particles to keep the pastry short and tender rather than tough.
- Baking powder
- Releases gas during baking to give the pastry a light lift.
- Egg yolk
- Adds richness and helps bind the dough together.
- Cold water
- Moistens the flour just enough to hold the dough together.
The step that matters
Roll out once only. Handling and kneading the dough develops gluten, which makes pastry tough. Keeping the dough cold, mixing only enough water, and rolling once preserves a short, tender texture.
