Why it works: Raisin and flour 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 ↓
Suet Pudding
Ingredients
Directions
Make the pudding
In a large bowl, combine suet or butter, molasses, raisins, currants, flour, sour milk, and baking soda, and mix until well combined.
Grease a pudding bag and fill it with the mixture.

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
- Suet or butter
- Adds fat that enriches the crumb and keeps the pudding moist during steaming.
- Flour
- Forms the structure that holds the pudding together as it sets.
- Molasses
- Adds sweetness, dark colour and a moist, rich texture.
- Sour milk
- Provides acidity that reacts with the baking soda to lift the pudding.
- Baking soda
- Reacts with the acidic sour milk to produce gas that leavens the batter.
- Raisins
- Add chewy pockets of sweetness and moisture throughout the pudding.
The step that matters
Keep the pudding boiling for the full time. Steaming in a sealed bag needs steady, continuous heat to cook the flour and set the batter through. If the water drops below a simmer, the pudding cooks unevenly and may turn out dense or gummy.
Swap the currant
How well each one fits the dish's main ingredients (butter, molasses, raisin, flour, milk):

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