Ingredients
Directions
Prepare
Clean the fruit and seed the raisins.
Chop the suet finely, peel and grate the apples, and grate the lemon and orange rinds.

Mix and cook

Transfer the mixture into a greased pudding mold or a well-floured pudding cloth.
Steam or boil for twelve hours without adding milk or water.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Eggs
- Bind the mixture and add structure as they set during steaming.
- Flour
- Provides the body that holds the dense pudding together.
- Suet
- Adds richness and moisture, keeping the pudding tender as it steams.
- Bread crumbs
- Absorb moisture and lighten the texture of the dense batter.
- Sugar
- Adds sweetness and helps the fruit flavours stand out.
- Baking powder
- Releases gas that gives the pudding some lift.
The step that matters
Steam or boil for twelve hours without adding milk or water. Long, gentle steaming cooks the dense mixture through evenly. Adding liquid during cooking would make the pudding soggy and change its texture, so the pot must be kept topped up with boiling water from outside the mold only as needed.
