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 dough with the flour.
Beat the dough with a rolling pin until smooth.
Shape and bake
Roll the dough thin and cut it into round biscuits.
Prick the biscuits all over with a fork.
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.

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.

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 when combined with liquid.
- Butter
- Adds fat, which tenderises the biscuits and adds richness.
- Skimmed milk
- Provides the liquid that hydrates the flour into a stiff dough.
The step that matters
Beat the dough with a rolling pin until smooth. Working the dough develops gluten, which gives a firm, cohesive texture. Overworking it makes the biscuits tough, so beat only until the dough is smooth and no longer cracked or crumbly.
“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.
