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 ↓
Egg Biscuits
Ingredients
Directions
The book says “a hot oven”. The 400°F (200°C) in the steps is the modern equivalent, not the book's own figure.
Prepare the dough
Sift together flour, baking powder, salt, and sugar twice.
Cream butter and lard together, then mix into the dry ingredients using your fingertips.
Add milk mixed with egg whites, and stir with a knife until you have a very soft dough.
Place the dough on a floured surface and pat it out to ¾ inch thick.
Bake
Cut out biscuits and bake in a hot oven at 400°F (200°C) for 15 minutes.

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 that holds the biscuits together as they bake.
- Baking powder
- Releases gas in the heated dough, helping the biscuits rise and become light.
- Egg whites
- Add structure and help bind the soft dough while adding some lift.
- Butter
- Adds fat that tenderizes the crumb and contributes flavor and some browning.
- Milk
- Provides moisture that hydrates the flour and makes the dough soft.
The step that matters
Stir the dough only until it just comes together. Once the milk and egg whites are added, overmixing develops gluten in the flour, making the biscuits tough rather than tender. A very soft dough should be handled gently and briefly.
