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 ↓

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
- Sugar
- Sweetens the batter and helps cream with the butter to trap air.
- Butter
- Adds fat and richness, and creaming it with sugar gives the pudding a tender texture.
- Eggs
- Bind the batter and add structure as the pudding sets while cooking.
- Flour
- Provides the structure that holds the pudding together as it cooks.
- Raisins
- Add chewy pockets of sweetness and moisture throughout the pudding.
The step that matters
Adding the eggs one at a time. Adding eggs gradually lets each one emulsify fully into the creamed butter and sugar. Adding them all at once can cause the batter to curdle or separate, which affects the final texture.
“What each ingredient does” and “The step that matters” were written by Claude from this recipe’s own method and reviewed in samples by CompKitchen.
