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 Biscuit
Ingredients
Directions
The book says “a moderate oven”. The 350°F (175°C) in the steps is the modern equivalent, not the book's own figure.
Make the dough
Rub 1½ pounds of flour with 2 ounces of butter.
Add 2 well-beaten eggs and 1 tablespoon of salt.
Wet the mixture with sweet milk until combined.
Shape and bake
Roll out the dough to about ½ inch thick.
Cut into small cakes and place on buttered baking sheets.
Bake in a moderate oven at 350°F (175°C) for 45 minutes.

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 biscuit as it sets in the oven.
- Butter
- Coats the flour particles, giving the biscuit a tender, short texture.
- Eggs
- Bind the dough and add richness and structure to the crumb.
- Sweet milk
- Provides the moisture that brings the flour and fat into a workable dough.
The step that matters
Wet the mixture with sweet milk until combined. Once the flour is hydrated, further mixing or kneading develops gluten, which makes the biscuit tough and dense. Stop as soon as the dough holds together.
