Ingredients

Directions

The book says “a slow oven”. The 300°F (150°C) in the steps is the modern equivalent, not the book's own figure.

Prepare

  1. Combine the flour and egg yolk in a bowl.

  2. Add enough milk to form a stiff paste.

Shape

  1. Knead the mixture until smooth.

  2. Roll out the dough thinly and cut into round shapes.

  3. Prick each biscuit with a fork.

Bake

  1. Bake in a slow oven at 300°F (150°C) until golden.

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 as it sets in the oven.
Egg yolk
Adds richness and helps bind the dough together.
Milk
Hydrates the flour so it forms a workable, stiff paste.

The step that matters

Bake in a slow oven until golden. A slow oven dries the biscuits through gradually, so they firm up without over-browning. Baking too hot can scorch the outside before the centre is set and crisp.
