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 ↓
Citron Pudding
Ingredients
Directions
The book gives no oven temperature. The 400°F (200°C) in the steps was added when the recipe was transcribed, as a starting point.
Prepare
Preheat the oven to 400°F (200°C).
In a bowl, beat together the butter and sugar until well combined.
Make the filling
Add the finely chopped citron, eggs, and grated orange peel; mix well.
Bake
Pour the mixture into a prepared puff pastry shell.
Bake for 30 minutes or until set and golden brown.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Butter
- Adds richness and a tender, fat-based texture to the filling.
- Sugar
- Sweetens the filling and helps it cream with the butter for a smooth base.
- Citron
- Provides the main citrus flavour and chopped pieces of fruit throughout the filling.
- Eggs
- Set during baking to give the filling its firm, custard-like body.
- Puff pastry
- Forms the crisp, golden shell that holds the filling while it bakes.
The step that matters
Bake until set and golden brown. Eggs set as they heat, so underbaking leaves the filling runny in the middle, while overbaking can make it dry and tough. Check that the centre is firm and the pastry is golden before removing it.
Swap the orange
How well each one fits the dish's main ingredients (butter, sugar, egg):
- Vanillafits better
- Lemonfits better

Fit is the average pairing score against butter, sugar, egg. Candidates are from the same food group and used in at least 100 recipes.
