Why it works: Butter and lemon are a kitchen classic. They rank in the top 16% of all ingredient pairs, and cooks put them together in 41,227 recipes. Both carry 3-hexenal, which smells apple, fruity. The science ↓
Transparent Pudding
Ingredients
Directions
The book says “a moderately hot oven”. The 350°F (175°C) in the steps is the modern equivalent, not the book's own figure.
Make the filling
Beat the eggs well in a pan.
Add the sugar, butter, lemon rind, and lemon juice.
Stir over low heat until the mixture thickens.
Pour the mixture into a basin and let it cool.
Bake
Line the edge of a buttered pudding dish with puff pastry.
Pour the pudding mixture into the dish.
Bake in a moderate oven at 350°F (175°C) for 45 minutes.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Eggs
- Set the custard as they cook and thicken the mixture into a sliceable filling.
- Butter
- Adds richness and a smooth, silky mouthfeel to the filling.
- Finely powdered sugar
- Sweetens the filling and dissolves easily into the warm mixture.
- Lemon juice
- Adds acidity that brightens the flavour and balances the sweetness.
- Puff pastry
- Forms a crisp, flaky edge around the custard as it bakes.
The step that matters
Stir over low heat until the mixture thickens. Eggs thicken when heated gently; too much heat can scramble them into lumps, so keep the heat low and stir constantly.
Swap the lemon
How well each one fits the dish's main ingredients (egg, sugar, butter):
- Vanillafits better
- Lemonthe original
- Raisinfits about as well
- Figfits about as well
Fit is the average pairing score against egg, sugar, butter. Candidates are from the same food group and used in at least 100 recipes.
