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 ↓

Flour and milk barely smell alike, yet cooks put them together in 78,219 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
- Flour
- Forms the bulk and structure of the pudding as it steams.
- Molasses
- Adds sweetness, dark colour and moisture to the batter.
- Beef suet
- Adds fat that keeps the pudding moist and tender.
- Sour milk
- Supplies liquid and acidity that reacts with the leavening.
- Cream of tartar
- Acidic salt that reacts with baking soda to help the pudding rise.
- Baking soda
- Reacts with the acid in the sour milk and cream of tartar to produce gas for lift.
The step that matters
Steam for the full 3 to 4 hours with a well-fitting cover. Steaming gently and steadily cooks the dense batter through. A loose cover lets steam escape and water level drops, so the pudding can end up dry or underbaked in the centre.
