Why it works: Butter and milk 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 moderate oven”. The 350°F in the steps is the modern equivalent, not the book's own figure.
Make the dough
Dissolve the butter in the milk.
Add the dissolved butter to the flour, sugar, egg, and ammonia.
Sift the ammonia with the flour before mixing.
Shape and bake
Roll out the dough to ¼ inch thick.
Cut into fingers 1 inch wide and 3 inches long.
Brush with egg or leave plain.
Bake in a moderate oven (350°F / 175°C) until golden.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- All-purpose flour
- Forms the main structure of the dough as its proteins set during baking.
- Butter
- Adds fat that shortens gluten strands, giving a tender, crumbly texture.
- Sugar
- Adds sweetness and helps the biscuits brown evenly in the oven.
- Egg
- Binds the dough and adds richness, and brushing it on helps browning.
- Milk
- Provides moisture that hydrates the flour and keeps the dough workable.
- Carbonate of ammonia
- Releases gas when heated, leavening the biscuits so they rise and lighten.
The step that matters
Sift the ammonia with the flour before mixing. Carbonate of ammonia releases gas as it heats. If it is not evenly distributed through the flour, it can leave pockets of uneven rising and patchy texture.
“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.
