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 ↓
Old-fashioned Plum Pudding
Ingredients
Directions
Prepare
Mix the bread crumbs with enough milk or water to moisten.
Combine all ingredients in a large bowl.
Grease a pudding bowl and fill it with the mixture.
Tie a cloth firmly over the top, leaving room for the pudding to swell.
Cook and store
Boil for 6 hours.
Store in a cool place; it can be reboiled later.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Flour
- Forms the bulk of the structure, setting as the pudding cooks.
- Eggs
- Bind the mixture and help it set firm when cooked.
- Baking powder
- Releases gas to lighten the pudding and help it rise as it swells.
- Suet
- Adds fat for richness and a moist, tender crumb.
- Molasses
- Adds sweetness, dark colour and a deep, slightly bitter flavour.
- Raisins
- Add sweetness and chewy texture throughout the pudding.
The step that matters
Tie the cloth firmly, leaving room to swell. The pudding expands as it cooks and the baking powder releases gas. A cloth tied too tightly leaves no room for expansion, which can crack the pudding or make it dense, while a loose seal lets water into the pudding during boiling.
