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 its gluten network sets.
- Butter
- Coats the flour particles, giving the pastry a tender, short texture and rich flavour.
- Rice flour
- Contains no gluten, so it makes the pastry finer and more crumbly.
- Caster sugar
- Adds sweetness and helps the pastry brown lightly.
- Egg yolk
- Adds fat and richness and helps bind the dough.
- Baking powder
- Releases gas to give the pastry a slight lift and lighter texture.
The step that matters
Mix with cold water to form a very stiff paste. Adding too much water or working the dough for too long develops gluten, which makes the pastry tough. Keeping the paste stiff and the water cold keeps the butter solid and the texture short.
