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 ↓

Flour and butter 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
- Bind the mixture and set the pudding as it cooks.
- Flour
- Thickens the batter so it holds together rather than running apart.
- Sugar
- Adds sweetness and helps the mixture beat to a smooth texture.
- Raisins
- Provide chewy bursts of sweetness and body throughout the pudding.
- Suet
- Adds richness and moisture, keeping the pudding tender during long boiling.
The step that matters
Tie the mold tightly in a cloth. A loose cloth lets water seep into the mold and dilute the batter, and the pudding can swell or break free. A snug wrap keeps the pudding compact and its texture even during the long boil.
Swap the raisin
How well each one fits the dish's main ingredients (egg, sugar, flour, veal, butter):
- Raisinthe original
- Lemonfits about as well
- Vanillafits less well
- Figfits less well
Fit is the average pairing score against egg, sugar, flour, veal, butter. Candidates are from the same food group and used in at least 100 recipes.
