Why it works: Butter and cream are a kitchen classic. They rank in the top 8% of all ingredient pairs, and cooks put them together in 41,516 recipes. Both carry delta-dodecalactone, which smells sweet, creamy. The science ↓

Ingredients
Directions
The book says “a brisk oven”. The 400°F (200°C) in the steps is the modern equivalent, not the book's own figure.
Prepare the dough
Mix the sugar and flour in a bowl.
Rub in the butter until the mixture resembles a stiff paste.
Add the whisked egg white and cream, mixing until combined.
Cover the paste and let it rest in a cool place for a short time.
Shape and bake
Divide the paste into small portions and roll each into thin rounds, about 2½ inches in diameter.
Bake on buttered baking sheets in a brisk oven at 400°F (200°C) for 3 to 4 minutes.

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 structure that holds the thin rounds together as they bake.
- Butter
- Rubbed into the flour to add richness and tenderness to the paste.
- Egg white
- Binds the paste and helps the thin rounds hold their shape.
- Sugar
- Adds sweetness and helps the biscuits brown as they bake.
The step that matters
Rolling the rounds thin. Thin rounds bake quickly and crisp evenly, while thick portions stay soft in the middle and may not set before the edges darken.
“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.
