Why it works: Flour and butter 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 moderate oven”. The 350°F (175°C) in the steps is the modern equivalent, not the book's own figure.
Prepare
Preheat the oven to 350°F (175°C).
Beat the eggs very lightly.
Melt the butter without oiling it.
Make the batter
Gradually add the sugar to the beaten eggs.
Fold in the flour and lemon rind, then add a pinch of salt.
Blend in the melted butter carefully.
Pour the mixture into buttered cups, filling them three parts full.
Bake and serve
Bake for 20 minutes.
Turn them out and serve immediately with wine sauce.

Flour and butter 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
- Beaten eggs provide the structure and lift that set the light pudding.
- Flour
- Gives the pudding body so it holds its shape once baked.
- Butter
- Adds richness and tenderness, and moisture to the crumb.
- Sugar
- Sweetens the pudding and helps tenderise the crumb.
The step that matters
Blend in the melted butter carefully. Folding gently keeps the air beaten into the eggs. Overmixing knocks out that air, so the pudding bakes up denser and less light.
Swap the lemon

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