Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Mutton
- Provides the main meat, which becomes tender during long, slow steaming.
- Suet paste
- Forms a sealed, sturdy crust that holds in moisture while the pudding steams.
- Flour
- Coats the meat, helping to thicken the juices into a rich gravy.
- Onion
- Adds savoury aroma and sweetness as it cooks into the meat juices.
The step that matters
Cover with paste and then with greased paper. The seal must be tight so steam and juices stay inside the basin. Greased paper lets the pudding expand as it cooks without the cover sticking or tearing.
Swap the onion
How well each one fits the dish's main ingredients (mutton, pepper, flour):

- Onionthe original
Fit is the average pairing score against mutton, pepper, flour. Candidates are from the same food group and used in at least 100 recipes.
