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 ↓
Sponge Pudding
Ingredients
Directions
The book says “a hot oven”. The 400°F (200°C) in the steps is the modern equivalent, not the book's own figure.
Prepare
Weigh four eggs in their shells to measure flour, sugar, and butter.
Sift the sugar and mix it with the flour.
Beat the butter until creamy and add it to the flour mixture.
Make the batter
Separate the yolks and whites of the eggs; beat them well separately.
Combine the beaten yolks and whites with the mixture and mix thoroughly.
Bake
Pour the batter into a mold and bake for about 30 minutes at 400°F (200°C).

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
- Whipped whites trap air and add lift, while yolks add richness and help bind the batter.
- All-purpose flour
- Forms the starch and gluten structure that holds the pudding together as it bakes.
- Sugar
- Adds sweetness and helps the batter brown lightly in the oven.
- Unsalted butter
- Adds fat for a tender crumb and rich flavor.
The step that matters
Beating the egg yolks and whites separately. Whites beaten to a stable foam trap air that expands in the oven and gives the sponge its lift. Under-beaten whites leave the pudding dense, while over-mixing after folding deflates the foam.
