Why it works: Flour and raisin match in chemistry and in kitchens. They rank in the top 1% of all ingredient pairs, and cooks put them together in 9,075 recipes. Both carry isobutyraldehyde, which smells malty, green. The science ↓

Ingredients
Directions
Make the batter
Combine the flour, sugar, suet, raisins, currants, grated potatoes, grated carrots, and baking soda in a large bowl and mix well until all ingredients are combined.
Transfer the mixture to a pudding mold or a heatproof dish.
Steam
Steam or boil for 3 hours until cooked through.

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):
- Figfits better
- Vanillafits better
- Orangefits better
- 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.
