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 ↓
Fruit Sponge 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 the batter
Preheat the oven to 350°F (175°C).
In a bowl, beat the eggs until fluffy.
Add baking powder, sugar, lemon extract, and vanilla extract; mix well.
Gradually add flour and cold water, mixing until smooth.
Divide the batter into two greased cake pans and bake until golden.
Make the filling and icing
For the filling, combine minced orange, chopped pineapple, sliced banana, ¾ cup sugar, and lemon juice.
For the icing, boil pineapple syrup with sugar in a 2:1 ratio until thick.
Beat two eggs for each cup of sugar until stiff, then gradually pour the hot syrup over the eggs.
Cook the mixture over steam until it reaches the right consistency to ice the cake.
Assemble
Spread the filling between the layers and ice the top with the prepared icing.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Eggs
- Whipped to create air, giving the sponge its light, airy structure.
- Flour
- Provides the structure that sets the batter once baked.
- Baking powder
- Releases gas in the batter, helping the cake rise.
- Sugar
- Sweetens the cake and helps the icing thicken into a stable syrup.
- Pineapple
- Adds moisture and fruity sweetness to the filling.
The step that matters
Pouring the hot syrup over the eggs. Pouring the syrup too quickly can scramble or deflate the beaten eggs. Adding it slowly while beating keeps the foam stable so the icing sets smooth and light.
