Breakfast Biscuit

Oven, in the book's wordsA quick oven

Ingredients

1 piece of risen bread dough
1 beaten egg
1 teaspoon butter
cream for greasing the tin

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

Work the beaten egg and butter into the risen bread dough until well combined.
Flour your hands and shape the dough into balls the size of an egg.

Bake and serve

Grease a tin with cream and place the biscuits on it.
Bake in a 400°F (200°C) oven for 20 minutes.
Serve hot for breakfast, breaking them open to eat.

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

What each ingredient does

Risen bread dough: Provides the main body and light, airy crumb as the biscuits bake.
Beaten egg: Adds richness and helps bind the dough, contributing to a tender structure and golden colour.
Butter: Adds fat for softness and flavour in the finished biscuits.
