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 ↓
To Make a Rich Plum Cake
Ingredients
Directions
The book says “a hot oven”. The 400°F in the steps is the modern equivalent, not the book's own figure.
Make the batter
Melt the butter until creamy, then mix in the sugar until light.
Add the allspice and cinnamon, stirring well.
Incorporate the egg yolks, two or three at a time.
Beat the egg whites until stiff and fold them in gradually.
Add the orange peel, lemon, citron, currants, and sweet almonds, mixing well.
Sift in the flour and add the brandy, mixing until combined.
Bake
Pour the batter into a tin hoop and bake in a hot oven (400°F / 200°C) for three hours, placing twelve sheets of paper underneath to prevent burning.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Butter
- Creamed with sugar to trap air, giving the cake a rich, tender crumb.
- Eggs
- Yolks enrich and bind the batter, while whipped whites lighten it with trapped air.
- Flour
- Forms the structure that holds the cake together as it sets in the oven.
- Sugar
- Aids aeration when creamed with butter, and adds sweetness and browning.
- Currants
- Provide concentrated fruit sweetness and chewy texture throughout the cake.
- Brandy
- Adds aroma and moisture to the batter.
The step that matters
Folding in the egg whites. Fold the stiff egg whites in gradually so the air they hold is not knocked out, keeping the cake light.
