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 Crust

Ingredients

Directions

Make the dough

  1. In a bowl, mix flour and butter until crumbly.

  2. Add castor sugar and mix well.

  3. Make a well in the center and add the egg yolk.

  4. Sprinkle salt over the egg yolk.

  5. Add lemon juice and cold water.

  6. Mix with fingers until a stiff paste forms.

Shape the pastry

  1. Flour your hands and the board to prevent sticking.

  2. Knead the paste lightly with your knuckles.

  3. Roll out the paste to the desired size and thickness.

  4. For a fruit tart, roll to fit the pie dish, slightly larger than the dish.

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 as it binds with the liquid.
Butter
Coats the flour so the pastry turns short and crumbly rather than tough.
Egg yolk
Adds richness and helps bind the dough together.
Castor sugar
Adds sweetness and contributes to browning in the baked crust.

The step that matters

Mix with fingers until a stiff paste forms. Overworking the dough develops gluten and makes the pastry tough. Keep the mixing brief and the butter cool so the crust stays short and tender.

Swap the lemon

How well each one fits the dish's main ingredients (flour, butter, sugar, egg):

  4. Lemonthe original

Fit is the average pairing score against flour, butter, sugar, egg. Candidates are from the same food group and used in at least 100 recipes.
