Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Haddock
- Forms the main body of the pudding and gives it its flaky, tender texture.
- Eggs
- Bind the fish and crumbs together and set when cooked, giving the pudding structure.
- Bread crumbs
- Absorb moisture and help the mixture hold together without becoming wet.
- Veal suet or marrow
- Adds fat that keeps the pudding moist and rich during boiling.
The step that matters
Pound the mixture well together. Thorough pounding breaks the fish fibres and blends the fat, eggs and crumbs into an even paste. Uneven mixing leaves pockets that can crumble or set unevenly when boiled.
Swap the white pepper
How well each one fits the dish's main ingredients (haddock, egg, parsley, onion, bread, veal):
- Capersfits better
- Garlicfits better
- Thymefits better
- White pepperthe original
Fit is the average pairing score against haddock, egg, parsley, onion, bread, veal. Candidates are from the same food group and used in at least 100 recipes.
