Why it works: Lemon and orange match in chemistry and in kitchens. They rank in the top 1% of all ingredient pairs, and cooks put them together in 10,634 recipes. Both carry 3-hexenal, which smells apple, fruity. The science ↓
A Small Rich Plum Cake
Ingredients
Directions
Prepare
Wash and pick the currants clean, then dry them and rub a little flour with them.
Cream the butter with your hand in a copper preserving pan.
Make the batter
Whisk the eggs (yolks and whites) for about 10 minutes in another pan.
Add the powdered sugar to the eggs and whisk over low heat, being careful not to burn.
Once warm, remove from heat and whisk until cold.
Mix the egg mixture with the creamed butter by hand.
Add the currants, flour, citron, lemon and orange peel, sweet almonds, and bitter almonds.
Stir in the cinnamon, mace, and brandy.
Bake
Prepare a cake pan with parchment paper and pour in the batter.
Bake in a regular heat oven until done.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Eggs
- Whisked and warmed, they build the aerated structure that holds the cake together.
- Butter
- Creamed with the mixture, it adds richness and a tender crumb.
- Flour
- Provides the starch and structure that sets the cake as it bakes.
- Powdered sugar
- Sweetens the batter and helps give the eggs a smooth, stable body.
- Currants
- Add fruity sweetness and chewy pockets throughout the cake.
- Brandy
- Adds aroma and flavour to the batter.
The step that matters
Whisking the eggs and sugar over low heat. Heating the eggs gently thickens and stabilises the foam, but too much heat will scramble or cook the eggs, ruining the batter's texture.
