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 ↓
Castle Pudding
Ingredients
Directions
The book gives no oven temperature. The 400°F (200°C) in the steps was added when the recipe was transcribed, as a starting point.
Prepare
Preheat the oven to 400°F (200°C).
Cream the butter and sugar together until light and creamy.
Beat in the egg until well combined.
Sift the flour and baking powder together, then add the grated lemon rind and stir lightly.
Fill buttered ramekins or molds three-quarters full with the mixture.
Cook and serve
Bake for 20 minutes or until golden.
Turn out and serve with wine or jam sauce.
Omit the lemon rind.
Steam for 50 minutes.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Butter
- Creaming with sugar traps air and gives a tender, rich crumb through its fat.
- Sugar
- Sweetens the pudding and, creamed with butter, helps lighten the batter.
- Egg
- Adds structure and binds the batter while adding moisture and richness.
- Flour
- Provides the structure that holds the pudding's shape as it sets.
- Baking powder
- Releases gas during cooking, making the pudding rise and become light.
The step that matters
Fill the ramekins three-quarters full. The baking powder makes the batter rise as it cooks. Leaving room in each mold lets it expand without overflowing or becoming dense.
Swap the lemon
The recipe marks lemon as optional. How well each one fits the dish's main ingredients (egg, butter, sugar, flour):

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