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 ↓
Black Pudding
Ingredients
Directions
Make the batter
In a bowl, combine the warm water and molasses.
Add the baking soda and stir until dissolved.
Mix in the salt and flour, then add the beaten egg, stirring vigorously after each addition.
Stone and coarsely chop the raisins, then fold them into the mixture.
Steam and serve
Butter a pudding mold or basin, pour in the mixture, and place it in a steamer over boiling water.
Steam for 2 hours.

Flour and egg barely smell alike, yet cooks put them together in 106,462 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
- Provides dark color, moisture, and a rich, slightly bitter sweetness.
- Flour
- Forms the structure that holds the pudding together as it sets.
- Egg
- Binds the batter and helps it set firm during steaming.
- Baking soda
- Reacts with the acidic molasses to produce gas that lightens the batter.
- Raisins
- Add chewy texture and concentrated sweetness throughout the pudding.
The step that matters
Adding the baking soda to the molasses mixture. Baking soda must be fully dissolved so it reacts evenly with the acidic molasses. Uneven dissolving leaves dense pockets or bitter spots and uneven rising.
