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 sharp oven”. The 400°F (200°C) in the steps is the modern equivalent, not the book's own figure.
Prepare
Wash and pick the currants clean, then dry them well.
Rub a little flour among the currants to make them white.
Make the dough
On a clean surface, combine the currants and powdered sugar.
Add the sifted flour and fresh butter, then mix all ingredients together to form a paste.
Roll the paste to an eighth of an inch thick and cut into desired shapes.
Bake
Preheat the oven to 400°F (200°C).
Place two or three sheets of paper under the biscuits on the baking tray.
Bake until just browned, being careful not to overbake.

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
- Provides the structure that holds the biscuits together as they bake.
- Butter
- Adds richness and tenderness, and helps the paste hold together.
- Eggs
- Bind the paste and add structure and richness to the biscuits.
- Powdered sugar
- Sweetens the biscuits and blends smoothly into the paste.
- Currants
- Add fruity sweetness and chewy bits throughout the biscuits.
The step that matters
Bake until just browned. Overbaking dries out the biscuits and makes them hard, because moisture leaves the dough as it heats. Pulling them out when just browned keeps them tender.
Swap the currant
How well each one fits the dish's main ingredients (sugar, flour, butter, egg):
- Raisinfits better
- Vanillafits better
- Figfits better
- Currantthe original
Fit is the average pairing score against sugar, flour, butter, egg. Candidates are from the same food group and used in at least 100 recipes.
