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 quick oven”. The 400°F (200°C) in the steps is the modern equivalent, not the book's own figure.
Prepare the dough
Sift the flour and baking powder together.
Chop the butter into the flour until fine.
Beat the egg and mix it with the milk.
Make a hole in the flour, add the salt, and pour in the egg and milk mixture.
Mix into a soft dough, adding more milk if needed.
Shape and bake
Roll out the dough to ½ inch thick.
Cut into rounds and bake at 400°F (200°C) until golden.

Flour and butter 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
- Provides the main structure that holds the biscuits together as they bake.
- Baking powder
- Releases gas when heated, helping the biscuits rise and become light.
- Butter
- Chopped into the flour, it creates fat pockets that make the texture tender and flaky.
- Egg
- Adds richness and helps bind the dough while adding structure as it bakes.
- Milk
- Adds moisture that hydrates the flour and forms a soft, workable dough.
The step that matters
Mix into a soft dough, adding more milk if needed. Overworking the dough develops gluten and makes biscuits tough, while too little liquid leaves them dry and crumbly. Mix just until the dough holds together.
