Why it works: Raisin and flour 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 ↓

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Eggs
- Bind the mixture and help give the pudding its set structure as it cooks.
- Stale bread crumbs
- Soak up the liquid and add body, giving the pudding a soft, tender crumb.
- Suet
- Adds fat that keeps the pudding moist and rich as it steams.
- Molasses
- Adds sweetness, moisture, and a deep, dark flavor.
- Flour
- Helps thicken the mixture and gives it structure.
- Raisins
- Add concentrated sweetness and chewy texture throughout the pudding.
The step that matters
Boiling for 5 to 6 hours. The pudding must cook long and at a steady simmer so the eggs and starches set fully and the dense mixture heats through. Too little time leaves it wet and under-set.
