Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Suet
- Adds richness and moisture, keeping the crust tender and the filling juicy.
- All-purpose flour
- Forms the stiff paste that structures the crust and encloses the filling.
- Steaks
- Provide the meat filling, which becomes tender during long gentle boiling.
- Ketchup
- Adds acidity and sweetness that season the meat and filling.
The step that matters
Boil gently for about three hours, keeping it covered with water. Gentle simmering tenderises tough steak and cooks the crust through without toughening it. If the water drops and the pudding is exposed, the crust dries out and the filling cooks unevenly.
