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
The book gives no oven temperature. The 350°F (175°C) in the steps was added when the recipe was transcribed, as a starting point.
Prepare
Wash and pick the currants clean, then dry them and toss with a little flour.
In a copper pan, cream the butter with your hand.
Make the batter
In another bowl, whisk the eggs for about 10 minutes.
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 cool.
Mix the egg mixture with the creamed butter by hand.
Add the currants, flour, citron, lemon and orange peel, sweet and bitter almonds, cinnamon, mace, and brandy; mix well.
Bake
Line a cake pan with paper, pour in the batter, and bake in a moderate oven at 350°F (175°C) until done.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Eggs
- Whisked eggs give the batter structure and help it set as it bakes.
- Butter
- Creamed butter adds richness and a tender crumb to the cake.
- Flour
- Provides the structure that holds the fruit and batter together as the cake sets.
- Powdered sugar
- Sweetens the batter and helps it become smooth and tender.
- Currants
- Add fruitiness and moisture; tossing them in flour helps keep them suspended in the batter.
The step that matters
Whisking the eggs and sugar over low heat. Gentle heat warms the eggs so the sugar dissolves and the mixture thickens, but too much heat will scramble the eggs and make the batter grainy. Whisking until cool then stabilizes the foam before it is folded into the butter.
