Why it works: Orange and lemon 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 ↓
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.
Make the batter
Cream the butter until smooth, then mix in the sifted sugar.
Beat the egg yolks and whites separately for half an hour, then combine them.
Add the sifted flour, lemon zest, confit orange and lemon peel, mace, and nutmeg.
Stir in the brandy and orange flower water.
Add fruit and bake
Prepare a baking hoop.
Fold in the currants and stoned raisins.
Bake in a preheated oven at 350°F (175°C) for 2½ hours.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Butter
- Creamed with sugar, it traps air and gives the cake a rich, tender crumb.
- Eggs
- Whisked whites add lift and structure, while yolks add richness and help set the crumb.
- Sifted flour
- Provides the main structure that holds the cake together as it bakes.
- Sugar
- Sweetens the cake and helps create a fine, even texture when creamed with butter.
- Currants
- Add concentrated sweetness and chewy bursts of fruit throughout the cake.
- Stoned raisins
- Add chewy, sweet fruit pieces that moisten the crumb as the cake bakes.
The step that matters
Beating the egg yolks and whites separately. Beating the whites separately and folding them in traps air, which gives the cake lift. Beating for the full half hour helps build a stable foam, and combining them gently preserves that air.
Swap the mace
How well each one fits the dish's main ingredients (butter, sugar, egg, flour, orange, lemon, nutmeg):
- Cinnamonfits better
- Cardamomfits better
- Allspicefits better
- Macethe original
Fit is the average pairing score against butter, sugar, egg, flour, orange, lemon, nutmeg. Candidates are from the same food group and used in at least 100 recipes.
