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 ↓
Boiled Fruit Pudding
Ingredients
Directions
Prepare the batter
Sift the flour, baking soda, and salt together in a bowl.
Stir in the raisins and currants (or dates/prunes).
Cream the butter and gradually mix in the molasses and milk.
Beat the eggs until light, then combine the yolks and whites.
Pour the molasses mixture into the flour mixture and stir to combine.
Add the beaten eggs and mix until well combined.
Steam and serve
Butter a pudding boiler and pour in the pudding mixture.
Place the boiler in a kettle of boiling water, cover both, and boil for 2 hours.
Serve with foaming sauce.

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
- All-purpose flour
- Forms the structure that holds the pudding together as it steams.
- Baking soda
- Reacts with the molasses and creates gas that lightens the pudding.
- Eggs
- Bind the batter and add structure and richness to the crumb.
- Molasses
- Adds sweetness, dark color, and moisture with a deep flavor.
- Butter
- Adds richness and a tender texture to the batter.
- Raisins
- Add chewy sweetness and moisture throughout the pudding.
The step that matters
Keep the boiler covered and the water boiling for the full 2 hours. Steaming depends on steady heat and trapped moisture. If the water stops boiling or the lid is left open, the pudding cooks unevenly and may turn out dense and soggy.
Swap the currant
How well each one fits the dish's main ingredients (flour, raisin, butter, molasses, milk, egg):
- Vanillafits better

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