Why it works: Milk and butter are a kitchen classic. They rank in the top 7% of all ingredient pairs, and cooks put them together in 81,283 recipes. Both carry (z)-4-heptenal, which smells biscuit, cream. The science ↓
Boston Cup Pudding
Ingredients
Directions
The book says “a hot 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).
Make the batter
Cream the butter and brown sugar together until light and fluffy.
Beat in the egg, then add the grated lemon rind and flour.
Stir in the milk and finally the baking powder.
Pour the mixture into a buttered Yorkshire pudding tin.
Bake and serve
Bake for 20 to 25 minutes until golden.
Once cooled, split the pudding, spread a layer of raspberry jam between the halves, and serve.

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
- All-purpose flour
- Forms the main structure of the pudding as it bakes.
- Brown sugar
- Creams with the butter to add sweetness, moisture and a caramel note.
- Butter
- Creamed with the sugar to trap air, giving a tender crumb and rich flavour.
- Egg
- Binds the batter and adds structure and richness as it sets.
- Baking powder
- Releases gas in the batter, helping the pudding rise and become light.
- Milk
- Adds moisture and loosens the batter so it bakes evenly.
The step that matters
Creaming the butter and sugar. Beating softened butter with sugar until light and fluffy traps air bubbles that help the pudding rise and give a tender texture. Cold or melted butter will not hold this air well.
