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 ↓

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Flour
- Forms the main structure of the dough once mixed with liquid.
- Baking powder
- Releases gas that lifts the dough so it rises as it steams.
- Butter
- Rubbed into the flour to add tenderness and richness to the dough.
- Milk
- Hydrates the flour so the dough becomes soft and workable.
- Raisins
- Add pockets of sweetness and moisture within the rolled dough.
The step that matters
Roll up and steam. The roll must be tight and sealed so the filling stays inside and the dough cooks evenly in the steam. Steaming for the full time sets the dough through without the centre remaining raw.
