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 ↓

Directions
The book says “a hot oven”. The 400°F (200°C) in the steps is the modern equivalent, not the book's own figure.
Prepare the dough
Sift together the flour, salt, and baking powder.
Rub the butter into the dry mixture.
Moisten the mixture with cold water.
Shape and bake
Shape the dough and place it on a baking sheet.
Bake in a hot oven at 400°F (200°C) for 20 minutes.
Transcribed from a scanned cookbook and modernised for today's kitchens. Where the book gave no heat or time, or said "a moderate oven", the temperatures and times here may be modern equivalents rather than the book's own figures.

Shared aroma: eucalyptol (eucalyptus, herbal).
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 main structure that holds the biscuit's shape.
- Baking powder
- Releases gas in the oven, making the biscuits rise and become light.
- Butter
- Melts in the oven to create flaky layers and a tender crumb.
The step that matters
Rub the butter into the dry mixture. Keep the butter cold and leave it in small pieces. As the biscuits bake, the cold fat melts and leaves pockets that make them flaky rather than dense.
Swap the walnut
How well each one fits the dish's main ingredients (flour, butter):
- Almondfits better
- Macadamia nutfits better
- Cashew nutfits better
- Walnutthe original
Fit is the average pairing score against flour, butter. Candidates are from the same food group and used in at least 100 recipes.
“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.
