Why it works: Butter and flour are a kitchen classic. They rank in the top 12% of all ingredient pairs, and cooks put them together in 124,287 recipes. Both carry isobutyraldehyde, which smells malty, green. The science ↓

Ingredients
Directions
The book says “a gentle oven”. The 300°F (150°C) in the steps is the modern equivalent, not the book's own figure.
Make the filling
Melt butter and sugar over low heat until boiling.
Remove from heat and let cool slightly.
Mix flour with whisked and strained eggs until smooth.
Gradually add the egg mixture to the cooled butter and sugar.
Stir in grated rinds and juice of lemons.
Bake
Line a baking dish with puff pastry and pour in the mixture.
Bake in preheated oven at 300°F (150°C) for 1 hour.

Butter and flour barely smell alike, yet cooks put them together in 124,287 recipes: they work on texture and structure more than aroma.
Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Eggs
- Set the custard and add richness and structure as they cook.
- Butter
- Adds richness and a smooth, tender texture to the filling.
- Sugar
- Sweetens the filling and helps give it a smooth body.
- Lemons
- Provide the acidity and bright lemon aroma that define the pudding.
- Flour
- Helps thicken the filling and give it body.
The step that matters
Gradually add the egg mixture to the cooled butter and sugar. Adding hot or fast-mixed egg to warm fat and sugar can scramble the eggs; adding it gradually into a cooled base lets it blend smoothly before baking.
Swap the lemon
How well each one fits the dish's main ingredients (butter, sugar, flour, egg):

- Figfits about as well
- Lemonthe original
Fit is the average pairing score against butter, sugar, flour, egg. Candidates are from the same food group and used in at least 100 recipes.
