Why it works: Flour and butter are a kitchen classic. They rank in the top 12% of all ingredient pairs, and cooks put them together in 124,287 recipes. Both carry isobutyraldehyde, which smells malty, green. The science ↓

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
Cream the butter in a bowl.
Add the sugar, beaten egg, and baking powder; mix well.
Gradually add the flour and combine until a dough forms.
Roll out the dough to ½ inch thick.
Shape and bake
Cut into round shapes and prick the tops.
Sprinkle sugar on top of each biscuit.
Bake in a moderate oven at 350°F (175°C) until golden.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Flour
- Provides the structure that holds the biscuits together as they bake.
- Butter
- Adds richness and tenderness, and helps the dough hold together when creamed.
- Egg
- Binds the dough and adds richness and structure.
- Baking powder
- Releases gas in the dough to give the biscuits a light, lifted texture.
- Sugar
- Adds sweetness and helps the tops brown as the biscuits bake.
The step that matters
Gradually add the flour and combine until a dough forms.. Adding flour gradually and mixing only until combined keeps the dough from becoming tough. Overworking develops gluten, which makes biscuits dense and hard instead of tender.
“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.
