Why it works: Butter and flour 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 quick oven”. The 400°F (200°C) in the steps is the modern equivalent, not the book's own figure.
Prepare the dough
Beat the yolks of 8 eggs and the whites of 2 eggs well.
Mix with 4 ounces of warmed butter.
Knead in 1 pound of flour and 4 ounces of sugar to form a paste.
Shape and bake
Roll into thick biscuits and prick them.
Bake on tin plates at 400°F (200°C) until golden.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Egg yolks
- Add richness, binding the dough and contributing to its tender texture.
- Egg whites
- Add structure and help bind the dough as it sets in the oven.
- Butter
- Adds fat for tenderness and moisture, and rich flavour.
- Flour
- Provides the structure that holds the dough together and sets when baked.
- Sugar
- Adds sweetness and helps the surface brown during baking.
The step that matters
Bake until golden. Baking at the stated temperature until golden sets the dough and browns the surface. Underbaked biscuits stay pale and soft inside, while overbaking dries them out.
