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 ↓

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.
Mix the dough
Mix the butter with the dry flour and sugar.
Add the currants and powdered pimento.
Combine all ingredients thoroughly.
Bake
Butter a pan and pour in the mixture.
Bake in a 400°F (200°C) oven for about 3 hours.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Butter
- Adds richness and fat that keeps the crumb tender.
- Flour
- Provides the structure that sets as the cake bakes.
- Sugar
- Adds sweetness and helps the crust brown.
- Currants
- Add sweetness, moist pockets of fruit and chewy texture.
- Pimento
- Adds a warm, aromatic spiced flavour.
The step that matters
Baking for about 3 hours. This dense batter has little lift, so it relies on a long, steady bake to carry heat to the centre. Removing it too early can leave the middle wet and unset, while the outside may darken first.
Swap the currant
How well each one fits the dish's main ingredients (butter, flour, sugar):
- Raisinfits better
- Vanillafits better
- Figfits better
- Currantthe original
Fit is the average pairing score against butter, flour, sugar. Candidates are from the same food group and used in at least 100 recipes.
