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 ↓
Hard Biscuits
Ingredients
Directions
The book gives no oven temperature. The 400°F (200°C) in the steps was added when the recipe was transcribed, as a starting point.
Make the dough
Warm the butter in a small saucepan.
Add enough skimmed milk to the butter to make a stiff paste with the flour.
Beat the mixture until smooth.
Roll the dough thin and cut it into round biscuits.
Bake
Prick the biscuits with a fork to create holes.
Bake in a 400°F (200°C) oven for about six minutes.
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.

Butter and flour barely smell alike, yet cooks put them together in 124,287 recipes: they work on texture and structure more than aroma.
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 structure of the dough, setting into a firm, crisp biscuit when baked.
- Butter
- Adds fat that tenderises the dough and gives a rich flavour.
- Skimmed milk
- Binds the flour and butter into a stiff paste that can be rolled out.
The step that matters
Roll the dough thin. Thin dough bakes through quickly and dries into a crisp biscuit. Thick dough stays doughy in the middle and may not set properly within the short baking time.
“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.
