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

What each ingredient does

Flour
Provides the starch and gluten structure that holds the pudding together as it cooks.
Suet
Adds fat that keeps the pudding moist and tender while it steams.
Sugar
Adds sweetness and helps the pudding brown slightly at the edges.
Grated potatoes
Add moisture and starch, giving the pudding a soft, dense body.
Grated carrots
Add moisture and natural sweetness, giving the pudding a soft, dense body.

The step that matters

Steam or boil for the full 3 hours. Long, gentle moist heat is needed to cook the grated potatoes and carrots through and set the starch. Stopping early leaves the centre dense, dough-like, or undercooked.

Swap the currant

How well each one fits the dish's main ingredients (flour, sugar, raisin, potato, carrot):

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

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