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

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

  2. Rub the butter into the flour.

  3. Add the sugar and mix well.

Make the dough

  1. Beat the eggs and add them to the mixture.

  2. Dissolve the volatile salts in hot water, allow to cool, and add to the mixture.

  3. Add milk gradually until a firm dough forms.

  4. Roll the dough thin and cut into round cakes.

Finish and bake

  1. Wet the tops with milk and turn them onto pulverized sugar.

  2. Bake in the preheated oven until golden.

Transcribed from a scanned cookbook and modernised for today's kitchens. Where the book gave no heat or time, or said "a moderate oven", the temperatures and times here may be modern equivalents rather than the book's own figures.

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

What each ingredient does

All-purpose flour
Provides the structure that holds the biscuit together as it bakes.
Butter
Coats flour particles and adds fat, giving a tender, short crumb.
White sugar
Adds sweetness and helps the tops brown as they bake.
Eggs
Bind the mixture and add richness and structure to the dough.
Volatile salts
Release gas when heated, lifting the biscuits so they rise and lighten.
Milk
Adds moisture so the flour hydrates and the dough can be formed.

The step that matters

Dissolve the volatile salts in hot water, then let them cool. Volatile salts release gas and ammonia when heated. Dissolving them in hot water and cooling the solution before mixing lets them disperse evenly through the dough, so the leavening acts gradually and the biscuits rise uniformly rather than unevenly.
