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 ↓
Plum Pudding
Ingredients
Directions
Mix molasses, baking soda, sugar, chopped raisins, butter, flour, egg, spices, salt, and sweet milk in a large bowl until well combined.
Pour the mixture into a greased pudding mold.

The pairs that carry this dish. Each one is judged two ways: how much their aromas overlap, and how often cooks already put them together.

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
- Molasses
- Adds dark color, moisture and a deep, sweet flavor to the pudding.
- Baking soda
- Reacts with the molasses acidity to lift and lighten the batter as it steams.
- Flour
- Provides the structure that holds the pudding together as it sets.
- Egg
- Binds the batter and helps it set into a firm, cohesive texture.
- Butter
- Adds richness and tenderness to the crumb.
- Chopped raisins
- Add chewy pockets of sweetness and moisture throughout the pudding.
The step that matters
Steam the pudding for two hours. Steaming gently and steadily cooks the batter through without drying it out. Letting the water boil dry or lifting the lid too often lowers the steam and can leave the pudding dense or undercooked.
Swap the raisin
How well each one fits the dish's main ingredients (molasses, sugar, butter, flour, egg, milk):
- Raisinthe original
- Vanillafits about as well
- Figfits less well
- Peachfits less well
Fit is the average pairing score against molasses, sugar, butter, flour, egg, milk. Candidates are from the same food group and used in at least 100 recipes.
