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 ↓
Orange Sandwich
Ingredients
Directions
The book says “a moderate oven”. The 350°F (175°C) in the steps is the modern equivalent, not the book's own figure.
Make the cake
Preheat the oven to 350°F (175°C).
Cream the butter and sugar together.
Add the beaten eggs and flavorings.
Sift the baking soda, cream of tartar, and flour together.
Stir in the sifted mixture lightly with the milk.
Spread the batter in a flat tin and bake until golden.
Make the filling
Once cooled, split the cake open.
For the filling, mix cornflour with lemon juice.
Add boiling orange juice and sugar to sweeten, stir, and boil for five minutes.
Use the mixture when cool to spread between the cake layers.
Finish
Cover with water icing if desired.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Flour
- Forms the cake's structure once it is set by baking.
- Eggs
- Bind the batter and add structure and richness to the crumb.
- Butter
- Adds fat for a tender texture and rich flavour.
- Sugar
- Sweetens the cake and helps it brown as it bakes.
- Baking soda
- Reacts with the acid in the mixture to help the cake rise.
- Cornflour
- Thickens the orange juice filling so it spreads between the layers.
The step that matters
Boil the filling for five minutes. Cornflour only thickens fully when boiled, and it must be cool before spreading. Under-boiling leaves a thin filling that runs out of the layers.
Swap the orange
How well each one fits the dish's main ingredients (flour, sugar, butter, egg, milk, cream, lemon):
- Vanillafits better
- Raisinfits better
- Figfits better
- Orangethe original
Fit is the average pairing score against flour, sugar, butter, egg, milk, cream, lemon. Candidates are from the same food group and used in at least 100 recipes.
