Steam and serve

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

What each ingredient does

Sour milk or buttermilk
Provides acidity that reacts with the baking soda to lift the pudding.
Baking soda
Reacts with the sour milk to produce gas, helping the pudding rise and turn light.
Beef suet
Adds fat and richness, keeping the pudding moist and tender as it steams.
Bread crumbs
Absorbs liquid and gives the pudding a soft, tender crumb structure.
White flour
Provides the main structure that holds the pudding together as it steams.
Currants, raisins, and citron
Add chewy texture and concentrated fruit sweetness throughout the pudding.

The step that matters

Steam without lifting the lid. Lifting the cover lets steam escape and the temperature drop, which can stall the rise and leave the pudding dense and uneven.

Swap the currant

How well each one fits the dish's main ingredients (milk, flour, bread, beef, apple, raisin, sugar):

  1. Figfits better
  2. Vanillafits better
  3. Pearfits better
  4. Currantthe original

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