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.
Make the batter
Preheat the oven to 400°F (200°C).
In a bowl, mix the finely sifted sugar with the flour.
Beat the butter until creamy and add it to the flour mixture.
Separate the yolks and whites of the eggs.
Beat the yolks and whites separately.
Combine the beaten yolks and whites with the mixture and mix thoroughly.
Bake
Pour the batter into a mold or six small cups.
Bake for about 30 minutes.

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 for lift, and yolks add richness and help the pudding set.
- Flour
- Provides structure as its proteins set during baking.
- Sugar
- Adds sweetness and helps the top brown lightly in the oven.
- Butter
- Adds richness and tenderness through the fat it brings to the batter.
The step that matters
Combine the beaten yolks and whites with the mixture. The beaten whites hold the air that makes the pudding rise. Folding them in gently keeps that air; vigorous or prolonged mixing knocks it out, leaving a denser pudding.
“What each ingredient does” and “The step that matters” were written by Claude from this recipe’s own method and reviewed in samples by CompKitchen.
