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 grated orange rind.
Sift the baking soda, cream of tartar, and flour together.
Stir in the sifted ingredients lightly with the milk.
Spread the mixture in a flat tin and bake for 30-40 minutes.
Once cooled, split the cake open.
Make the filling
For the filling, mix cornflour with lemon juice, then add boiling orange juice and sugar to taste.
Stir and boil for five minutes, then let it cool.
Assemble and garnish
Spread the filling on the cake and cover with water icing if desired.
Blanch and slice almonds finely, and chop raisins if using.

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 baked.
- Eggs
- Bind the batter and add structure and richness to the crumb.
- Butter
- Adds fat for tenderness and flavour when creamed with sugar.
- Sugar
- Sweetens the cake and helps it brown while creaming aerates the batter.
- Baking soda
- Reacts with cream of tartar to produce gas that makes the cake rise.
- Cornflour
- Thickens the orange filling as it boils.
The step that matters
Stir in the sifted ingredients lightly with the milk. Overmixing once flour meets liquid develops gluten, which makes the cake tough. Stirring gently keeps the crumb tender and preserves the rising gas from the baking soda and cream of tartar.
