Ingredients

Directions

The book says “a hot oven”. The 400°F (200°C) in the steps is the modern equivalent, not the book's own figure.

Prepare the dough

  1. Mix the flour, baking powder, and salt in a bowl and sift twice.

  2. Rub in the lard and butter with your fingertips until well combined.

  3. Gradually add the milk and water, mixing with a knife to form a soft dough.

Shape and bake

  1. Roll out the dough to fit the top of the pan and press it neatly at the edges.

  2. Bake for 20 minutes in a hot oven at 400°F (200°C).

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.

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 crust as the gluten network sets during baking.
Lard
Coats flour particles to keep the crust tender and flaky.
Butter
Adds fat for flavour and helps create flaky layers in the crust.
Baking powder
Releases gas in the oven so the crust rises and lightens.
Milk and water
Hydrates the flour so the dough holds together and bakes up tender.

The step that matters

Rubbing in the lard and butter. Fat must stay in distinct pieces coated in flour, not fully blended in, so steam from the liquid separates layers and the crust turns flaky rather than dense.
