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 ↓
Rich Short Crust
Ingredients
Directions
The book gives no oven temperature. The 400°F (200°C) in the steps was added when the recipe was transcribed, as a starting point.
Prepare
Preheat oven to 400°F (200°C).
Lightly mix butter into flour in a bowl.
Add baking powder, sugar, and egg yolks.
If needed, add a little water to form a stiff paste.
Shape and bake
Roll out dough thinly and use immediately.
For fruit tarts, brush crust with cold water and sprinkle with castor sugar before baking.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Flour
- Forms the main structure of the pastry once mixed with liquid and fat.
- Butter
- Coats flour particles to keep the crust tender and flaky rather than tough.
- Egg yolks
- Add richness and help bind the dough together.
- Baking powder
- Releases gas in the oven to lighten the crust.
- Castor sugar
- Adds sweetness and helps the crust brown when sprinkled on top.
The step that matters
Adding water to the paste. Too much water develops gluten in the flour, making the crust tough instead of short and crumbly. Add only a little, just until the paste holds together.
“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.
