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
Separate the yolk from the egg white and break up the yolk.
Add lemon juice and cold water to the yolk.
Rub the butter into the flour until it resembles breadcrumbs.
Add the liquid to the dry flour, stirring with a knife or metal spoon.
Form the mixture into a large lump.
Shape the pastry
Sprinkle the board with rice flour and roll out the dough.
Cut the dough into long strips wide enough to fit the pie dish.
Butter the sides and bottom of the pie dish, then place the strips inside.
Wet the edges and decorate with twisted leaves.

Flour and butter barely smell alike, yet cooks put them together in 124,287 recipes: they work on texture and structure more than aroma.
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 the base for the dough.
- Butter
- Rubbed into the flour to create a tender, crumbly texture and add richness.
- Egg yolk
- Adds richness and helps bind the dough together.
- Cold water
- Moistens the flour so the dough holds together without developing too much gluten.
- Lemon juice
- Adds a little acidity that brightens flavour and tenderises the dough.
The step that matters
Adding the liquid to the flour. Stirring gently with a knife or metal spoon and using cold liquid keeps the butter in small pieces and limits gluten development, which keeps the pastry short and tender rather than tough.
Swap the lemon
How well each one fits the dish's main ingredients (flour, egg, butter):

- Lemonthe original
- Coconutfits about as well
Fit is the average pairing score against flour, egg, butter. Candidates are from the same food group and used in at least 100 recipes.
