Rock Scones

Oven, in the book's wordsA quick oven

Ingredients

1 lb all-purpose flour
2 teaspoons baking powder
¼ teaspoon salt
½ pint milk or buttermilk

Directions

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

Prepare the dough

Sift the flour, baking powder, and salt together.
Mix in the milk or buttermilk to form a moderately stiff paste.

Shape and bake

Break off pieces the size of walnuts and place them on a greased baking sheet.
Bake in a preheated oven at 400°F (200°C) for about 10 minutes.

What each ingredient does

All-purpose flour: Provides the structure that holds the scones together as they set.
Baking powder: Releases gas in the dough so the scones rise and lighten as they bake.
Milk or buttermilk: Hydrates the flour to form the paste and adds moisture and tenderness.
