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 ↓

Directions
The book says “a brisk oven”. The 400°F (200°C) in the steps is the modern equivalent, not the book's own figure.
Make the batter
Mix sifted sugar, fresh butter, egg whites, egg yolks, and flour together with your hands until well combined in an earthen pan.
Add picked currants and mix gently.
Bake
Drop spoonfuls of the mixture onto buttered tin plates.
Bake in a brisk oven at 400°F (200°C) until golden.
