Ingredients

Directions

The book says “a hot oven”. The 400°F (200°C) in the steps is the modern equivalent, not the book's own figure.

Make the dough

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

  2. In a large bowl, combine flour, milk, butter, ammonia, sugar, and lemon oil.

  3. Mix in the eggs until well combined.

Shape and bake

  1. Roll out the dough into long round strips.

  2. Cut the strips into diamond shapes and scallop the tops with the back of a knife.

  3. Place on greased baking pans and bake 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.

The flavor team

The pairs that carry this dish. Each one is judged two ways: how much their aromas overlap, and how often cooks already put them together.

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

What each ingredient does

Flour
Provides the main structure that holds the biscuit together as it bakes.
Eggs
Add structure and richness, setting as the biscuits bake.
Butter
Adds fat for tenderness and a rich flavor.
Sugar
Adds sweetness and helps the surface brown as it bakes.
Milk
Supplies moisture that hydrates the flour and keeps the dough workable.
Ammonia
Releases gas as it heats, helping the biscuits rise and become light.

The step that matters

Bake until golden. No bake time is given, so color is the guide. Browning comes from sugars and proteins reacting in the oven's heat, so pull the biscuits when golden rather than pale, and avoid over-browning.

Swap the lemon

How well each one fits the dish's main ingredients (flour, milk, butter, sugar, egg):

Fit is the average pairing score against flour, milk, butter, sugar, egg. Candidates are from the same food group and used in at least 100 recipes.
