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 ↓

Butter and flour barely smell alike, yet cooks put them together in 124,287 recipes: they work on texture and structure more than aroma.
Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Eggs
- Beaten eggs, with whites added last, give the pudding structure and lift.
- Baking soda
- Releases gas in the batter, helping the pudding rise and become light.
- Butter
- Creamed with the flour, it adds richness and a tender texture.
- Flour
- Forms the body of the pudding and sets as it cooks, giving it structure.
- Sweet raisins
- Provide sweetness and chewy pockets of fruit throughout the pudding.
The step that matters
Securing the bag so it does not touch the pot. If the bag touches the sides of the pot, the pudding can stick or cook unevenly where it contacts the hot metal, so it should hang freely in the boiling water.
Swap the raisin
How well each one fits the dish's main ingredients (butter, flour, egg, milk, whisky):
- Vanillafits about as well
- Raisinthe original
- Figfits about as well
- Applefits less well
Fit is the average pairing score against butter, flour, egg, milk, whisky. Candidates are from the same food group and used in at least 100 recipes.
