Why it works: Flour and almond are a kitchen classic. They rank in the top 5% of all ingredient pairs, and cooks put them together in 8,673 recipes. Both carry isobutyraldehyde, which smells malty, green. The science ↓
Rich Plum Cake
Ingredients
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.
Make the batter
Melt the butter until creamy.
Add the sugar and stir until light.
Mix in the allspice and cinnamon.
Stir for 15 minutes, then add yolks of eggs one at a time.
Beat the egg whites until stiff and fold them in gradually.
Add the orange peel, lemon peel, citron, and currants mixed with sweet almonds.
Fold in the sifted flour and brandy.
Bake
Bake in a tin hoop at 400°F (200°C) for 3 hours.
Place 12 sheets of paper underneath and 4-5 on top to prevent burning.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Butter
- Gives richness and a tender crumb as it is creamed with the sugar.
- Sugar
- Sweetens the cake and helps trap air when creamed with the butter.
- Eggs
- Provide structure, and beaten whites add air that helps the cake rise.
- Flour
- Forms the structure that holds the cake together as it sets.
- Currants
- Add fruit flavour and a chewy texture throughout the cake.
- Brandy
- Adds aroma and depth of flavour to the batter.
The step that matters
Folding in the beaten egg whites. Stiff whites hold air that lifts the batter. Folding gently and gradually keeps that air in, so the cake rises instead of turning dense.
