Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs

What each ingredient does

All-purpose flour
Provides the main structure that holds the pudding together as it steams.
Bread crumbs
Add bulk and absorb the liquid, giving the pudding a soft, moist body.
Suet
Adds fat that keeps the pudding rich and tender as it cooks.
Egg
Binds the mixture and helps it set firm when cooked.
Carbonate of soda
Reacts with the vinegar to produce gas that lightens the pudding.
Raspberry jam
Adds sweetness and fruity flavour throughout the pudding.

The step that matters

Tying the basin. The basin must be sealed carefully so steam cannot escape and water cannot enter. Steam trapped inside cooks the pudding evenly and keeps it moist during the long boil.

Swap the raspberry

How well each one fits the dish's main ingredients (flour, bread, sugar, vinegar, milk, egg):

Fit is the average pairing score against flour, bread, sugar, vinegar, milk, egg. Candidates are from the same food group and used in at least 100 recipes.
