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 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 coat them.
Preheat the oven to 400°F (200°C) and place parchment paper on baking sheets.
Make and shape the dough
In a bowl, combine the currants, powdered sugar, flour, and butter.
Break the eggs into the mixture and mix until it forms a paste.
Roll the paste on a floured surface to ⅛ inch thick.
Cut out shapes as desired.
Bake
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
- Currants
- Add fruit pieces and chewy bursts of sweetness throughout the biscuit.
- Powdered sugar
- Sweetens the dough and gives it a fine, tender crumb.
- Flour
- Provides the structure that holds the paste together and lets it be rolled and cut.
- Fresh butter
- Adds fat for richness and tenderness in the finished biscuit.
- Eggs
- Bind the mixture into a paste and add richness and structure.
The step that matters
Bake until just browned. Overbaking dries out the biscuit and turns it hard, because the sugar and butter brown quickly and little moisture remains to keep the crumb tender.
Swap the currant
How well each one fits the dish's main ingredients (sugar, flour, butter, egg):

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.
