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 Rich Plum-Cake
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.
Prepare
Preheat the oven to 400°F (200°C).
Cream the butter until smooth.
Make the batter
In a separate bowl, whisk the eggs with the sugar over a pan of hot water until warm.
Remove from heat and continue whisking until cool.
Combine the egg mixture with the creamed butter.
Add the currants, candied peel, bitter almond paste, sliced sweet almonds, cinnamon, mace, and liqueur.
Beat all ingredients together for 30 minutes.
Bake
Line a cake hoop with paper and pour in the batter.
Bake for 2 to 3 hours, then cool the oven and let the cake dry inside.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Eggs
- Whisked eggs trap air and bind the batter, giving the cake its structure.
- Butter
- Creamed butter adds richness and a tender crumb.
- All-purpose flour
- Flour provides the starch structure that holds the rich batter together as it bakes.
- Sugar
- Sugar adds sweetness and helps the batter brown during baking.
- Currants
- Currants add fruitiness and moisture to the cake.
- Sweet almonds
- Sliced almonds add texture and a nutty flavor.
The step that matters
Cool the oven and let the cake dry inside. Baking a dense, fruit-rich cake for 2 to 3 hours can over-brown the outside before the center sets. Lowering the heat and letting the cake dry in the cooling oven finishes the centre gently.
Swap the currant
How well each one fits the dish's main ingredients (flour, butter, egg, sugar, lemon, orange, almond):
