Why it works: Butter and milk are a kitchen classic. They rank in the top 7% of all ingredient pairs, and cooks put them together in 81,283 recipes. Both carry (z)-4-heptenal, which smells biscuit, cream. The science ↓
Short Crust for Tarts
Ingredients
Directions
Make the dough
In a bowl, lightly break 6 ounces of butter into 8 ounces of flour with minimal handling.
Add 2 teaspoons of powdered sugar and 1 to 2 tablespoons of water.
Roll the mixture for several minutes, folding it like puff pastry and handling it as little as possible.
Make the paste
In another bowl, crumble ½ pound of butter into 1 pound of flour, breaking it into small pieces.
Mix in a pinch of salt and 2 ounces of sifted sugar.
Add enough milk to form a very smooth and somewhat firm paste.
Bake
Bake slowly until pale and lightly golden.

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
- All-purpose flour
- Forms the main structure that holds the pastry together once baked.
- Unsalted butter
- Creates flaky, tender layers as it stays in small pieces within the flour.
- Powdered sugar
- Adds sweetness and helps the pastry brown lightly in the oven.
- Milk
- Adds moisture so the paste comes together smoothly and firmly.
The step that matters
Handle the dough as little as possible. Overworking develops gluten, which makes the pastry tough. Warmth from the hands also melts the butter, reducing the flaky texture.
“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.
