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

What each ingredient does

Suet
Adds richness and a tender, moist crumb as it melts during cooking.
Flour
Provides the structure that holds the pudding together.
Baking soda
Reacts with the vinegar and gives the pudding lift.
Egg
Binds the mixture and helps it set firm.
Milk
Moistens the dry ingredients into a batter.
Vinegar
Reacts with the baking soda to produce gas that aerates the pudding.

The step that matters

Stir in the vinegar last. Vinegar reacts with baking soda right away, releasing gas. Adding it at the end and moving the batter straight into the mold keeps that gas trapped so the pudding rises rather than going flat.

Swap the ginger

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

  1. Cinnamonfits better
  2. Nutmegfits better
  3. Capersfits better
  4. Gingerthe original

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