Ingredients

Directions

The book says “a moderate oven”. The 350°F (175°C) in the steps is the modern equivalent, not the book's own figure.

Prepare

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

Make and shape the dough

  1. In a bowl, combine flour, milk, sugar, melted butter, eggs, and baking powder. Mix until well combined.

  2. Shape the dough into small biscuits.

Rise and bake

  1. Place the biscuits on a baking sheet and let them rise.

  2. Bake until golden brown.

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 that holds the dough together as it bakes.
Eggs
Add structure and richness, helping the biscuits set and bind.
Baking powder
Releases gas in the oven, helping the biscuits rise and become light.
Butter
Adds fat for tenderness and flavour, and helps browning.
Sugar
Adds sweetness and helps the surface brown in the oven.
Milk
Provides moisture that hydrates the flour and forms the dough.

The step that matters

Bake until golden brown. Bake until the surface turns golden, not just until set. Browning comes from sugars and proteins reacting with heat, and it adds flavour and a crisp, dry crust that a pale, underbaked biscuit lacks.
