Directions

Make the batter

  1. Beat the butter and sugar together until creamy.

  2. Add the beaten eggs and vanilla, then mix in the flour and baking powder.

  3. Stir in enough milk to achieve a smooth batter.

Steam and serve

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs

What each ingredient does

Butter
Creams with sugar to trap air and give the pudding a tender, rich crumb.
Eggs
Add structure and richness, helping the batter set firm as it steams.
Flour
Forms the main structure of the pudding once it is cooked.
Baking powder
Releases gas during steaming so the pudding rises and stays light.
Castor sugar
Sweetens the batter and helps it cream to a light texture with the butter.

The step that matters

Stir in enough milk to achieve a smooth batter. Too little milk leaves a stiff batter that steams dense, while too much makes it loose and heavy. Aim for a smooth, pourable consistency so the pudding rises evenly and sets with a fine crumb.
