Ingredients

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.

Make the dough

  1. Cream the butter and sugar together until light and fluffy.

  2. Add the egg and mix well.

  3. Sift in the flour and baking powder, and mix until combined.

Shape and bake

  1. Place the mixture in a pastry bag or squirt bottle.

  2. Force the mixture onto a greased baking sheet.

  3. Bake in a 400°F (200°C) oven for 10 minutes.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs

What each ingredient does

Butter
Creaming butter with sugar traps air, giving the biscuits a light, tender texture and rich flavour.
Sugar
Creams with butter to aerate the dough and adds sweetness and gentle browning.
Flour
Provides the structure that holds the biscuit shape as the dough sets in the oven.
Egg
Binds the creamed butter and sugar into a smooth dough and adds structure as it sets.
Baking powder
Releases gas in the oven, helping the biscuits rise and become lighter in texture.

The step that matters

Creaming the butter and sugar. Beating until light and fluffy traps air in the fat. That air expands in the oven and helps set the texture. Under-creaming leaves dense biscuits, while the dough should be mixed only until combined once the flour is added to avoid toughening.
