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 ↓

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Eggs
- Whites trap air for lightness while yolks add richness and help bind the batter.
- Flour
- Provides the structure that holds the pudding together as it cooks.
- Butter
- Adds richness and a tender texture to the batter.
- Suet
- Adds fat that keeps the pudding moist and rich during long boiling.
- Sugar
- Adds sweetness and helps the batter become light when creamed with butter.
- Raisins
- Provide chewy sweetness and moisture throughout the pudding.
The step that matters
Folding in the beaten egg whites. Whites hold air that gives lightness. Folding gently keeps that air in the batter, while vigorous stirring would deflate it and make the pudding dense.

Fit is the average pairing score against butter, sugar, flour, raisin, egg, milk, brandy. Candidates are from the same food group and used in at least 100 recipes.
