Lemon Biscuits

Oven, in the book's wordsA quick oven

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.

Prepare the dough

  1. Preheat your oven to 400°F (200°C).

  2. Beat the butter and sugar together until creamy.

  3. Work in the flour and grated lemon peel.

  4. Mix in half of a well-beaten egg.

Shape and bake

  1. Flour a surface, turn the dough onto it, and roll it very thin.

  2. Cut out biscuits using round or fancy cutters.

  3. Brush a clean baking sheet with melted butter.

  4. Lay the biscuits on the sheet and bake until crisp.

  5. Cool the biscuits on a sieve, then store in a dry tin.

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

What each ingredient does

Butter
Creamed with sugar, it adds richness and a tender, crumbly texture to the biscuits.
Castor sugar
Beaten with the butter, it adds sweetness and helps create a light, creamy base.
Flour
Forms the structure of the dough, which sets and holds its shape when baked.
Egg
Binds the dough and adds moisture and richness to the biscuits.

The step that matters

Roll the dough very thin. Thin dough has little moisture and bakes quickly, so it turns crisp rather than soft. Thick dough stays doughy in the middle and may not crisp evenly.
