Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Mackerel
- Forms the main body of the filling and provides rich, savoury flavour.
- Pickled pork
- Adds salty, fatty richness that keeps the filling moist during boiling.
- Suet crust
- Encloses the filling and forms a soft, tender pastry that steams as it cooks.
The step that matters
Boil for 1 hour or more, depending on size. The pudding must cook long enough for the fish to become fully cooked through and the suet crust to steam until tender. Larger pieces need more time, so check the size before judging doneness.
Swap the parsley
How well each one fits the dish's main ingredients (fish, pork, pepper):
- Thymefits about as well
