Why it works: Milk and butter are a kitchen classic. They rank in the top 7% of all ingredient pairs, and cooks put them together in 81,283 recipes. Both carry (z)-4-heptenal, which smells biscuit, cream. The science ↓

Ingredients
Directions
The book says “a quick oven”. The 400°F in the steps is the modern equivalent, not the book's own figure.
Prepare the dough
In a basin, combine sugar and milk; let it stand for 2 hours, stirring occasionally.
Rub butter into flour, creating a well in the center.
Add carbonate of ammonia and beaten egg to the milk mixture; stir and mix into a smooth dough.
Cover and let it stand for a few minutes.
Shape and bake
Roll out to ½ inch thick, cut with a round cutter, and place on buttered baking sheets.
Brush with milk and bake in a quick oven (400°F / 200°C) until golden.

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 of the biscuits as its proteins and starch set in the oven.
- Butter
- Adds fat that tenderises the crumb and helps the biscuits brown.
- Egg
- Binds the dough and adds richness and structure to the biscuits.
- Carbonate of ammonia
- Releases gas as it heats, helping the biscuits rise and become light.
- Loaf sugar
- Sweetens the biscuits and contributes to browning in the oven.
The step that matters
Let the dough stand before rolling. Resting lets the flour hydrate and the leavening begin to work, so the dough is easier to roll and the biscuits bake up lighter rather than dense.
“What each ingredient does” and “The step that matters” were written by Claude from this recipe’s own method and reviewed in samples by CompKitchen.
