Why it works: Butter and milk 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 ↓
Railway 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 the batter
Preheat the oven to 400°F (200°C).
Rub the butter into the flour.
Add the sugar, beaten egg, and milk.
Beat well and then mix in the baking powder.
Bake and fill
Pour the mixture into a greased baking tin and bake for 20 minutes.
Spread jam over one half and fold the other half over it.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Flour
- Forms the main structure of the pudding as it sets in the oven.
- Butter
- Rubbed into the flour to add fat, giving a tender, crumbly texture.
- Egg
- Binds the mixture and adds structure and richness.
- Baking powder
- Releases gas in the batter, helping it rise in the oven.
- Sugar
- Adds sweetness and helps the crust brown.
- Milk
- Adds moisture and loosens the batter.
The step that matters
Mix in the baking powder after beating. Baking powder starts releasing gas once it meets liquid, so it should be mixed in just before baking. Overbeating after it is added can knock out gas and reduce rise.
