Why it works: Flour and butter are a kitchen classic. They rank in the top 12% of all ingredient pairs, and cooks put them together in 124,287 recipes. Both carry isobutyraldehyde, which smells malty, green. The science ↓

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Flour
- Forms the main structure of the pudding as it sets during cooking.
- Butter
- Rubbed into the flour to add richness and a tender texture.
- Eggs
- Bind the mixture together and help it set firm when cooked.
- Baking powder
- Releases gas during cooking so the pudding rises and becomes lighter.
- Currants
- Add concentrated sweetness and chewy fruit texture throughout the pudding.
- Sultanas
- Add concentrated sweetness and chewy fruit texture throughout the pudding.
The step that matters
Boil or steam for 4 hours. Long, gentle, steady heat is needed to cook the egg and flour mixture through without drying it out. Water in the basin should be kept boiling or steaming throughout, since heat loss would leave the centre underset.
Swap the currant
How well each one fits the dish's main ingredients (flour, sugar, butter, egg, lemon):

- Vanillafits better
- Figfits better
- Currantthe original
Fit is the average pairing score against flour, sugar, butter, egg, lemon. Candidates are from the same food group and used in at least 100 recipes.
