Pastry, Biscuit Crust

Ingredients

Directions

The book gives no oven temperature. The 350°F (175°C) in the steps was added when the recipe was transcribed, as a starting point.

  1. Preheat the oven to 350°F (175°C).

  2. Rub the butter into the flour until well combined.

  3. Add the sugar and salt, then mix in the beaten egg yolk.

  4. Gradually add a little water and knead until smooth.

  5. Roll out the dough and use as desired.

Transcribed from a scanned cookbook and modernised for today's kitchens. Where the book gave no heat or time, or said "a moderate oven", the temperatures and times here may be modern equivalents rather than the book's own figures.

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 dough once it is bound with liquid.
Butter
Rubbed into the flour to add tenderness and a crumbly, rich texture.
Egg yolk
Adds richness and helps bind the dough together.
Sugar
Adds sweetness and contributes slight browning during baking.

The step that matters

Gradually add the water. Adding water slowly lets the flour absorb it evenly. Too much liquid at once makes the dough sticky and tough, because gluten develops more when the dough is overworked.
