Why it works: Butter and egg are a kitchen classic. They rank in the top 17% of all ingredient pairs, and cooks put them together in 118,967 recipes. Both carry decanal, which smells soap, orange peel. The science ↓
Orange Cheesecakes
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 the filling
Squeeze the juice of the Seville orange onto the sponge cake.
Boil the orange rind, changing the water 3-4 times to remove bitterness.
Pound the rind with the sugar until fine and smooth.
Make the custard
In a saucepan, combine the pounded mixture, melted butter, egg yolks, and egg whites.
Cook over low heat until thickened.
Bake and serve
Line patty pans with puff pastry and half-fill them with the mixture.
Bake in a 400 °F (200 °C) oven until golden.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Egg yolks
- Thicken the mixture and enrich it as it cooks to a set custard.
- Egg whites
- Add structure and help the custard set as it cooks.
- Butter
- Adds richness and a smooth, tender texture to the filling.
- Lump sugar
- Sweetens the filling and balances the bitterness of the orange rind.
- Seville orange
- Provides acidity and fragrant citrus flavour to the filling.
The step that matters
Cook over low heat until thickened. Egg proteins set at moderate temperatures, and high heat can curdle the custard. Cooking gently over low heat and stirring keeps the mixture smooth while it thickens.
Swap the orange
How well each one fits the dish's main ingredients (sugar, butter, egg):
- Vanillafits better
- Lemonfits better
- Raisinfits better
- Orangethe original
Fit is the average pairing score against sugar, butter, egg. Candidates are from the same food group and used in at least 100 recipes.
