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 quick oven”. The 400°F (200°C) in the steps is the modern equivalent, not the book's own figure.
Make the dough
In a basin, combine the butter, salt, and sugar.
Pour boiling water over the mixture and stir until the butter melts.
Add the flour and mix to form a stiff dough.
Beat the dough well with a rolling pin.
Bake
Roll it very thin, cut into shapes, and bake in a 400°F (200°C) oven until pale brown.

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
- Flour
- Forms the structure of the dough, setting into a firm, crisp biscuit as it bakes.
- Butter
- Adds fat that melts into the dough, giving a short, tender texture.
- Sugar
- Adds sweetness and helps the biscuits brown during baking.
The step that matters
Roll the dough very thin. Thin dough dries out and crisps quickly in the oven, while thicker pieces stay soft and bake unevenly. Even thickness also helps the biscuits brown at the same rate.
“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.
