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 butter 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
- Flour
- Provides the starch and gluten network that gives the pudding its body.
- Baking soda
- Reacts with the acidic sour milk to release gas that lightens the pudding.
- Sour milk
- Its acidity activates the baking soda and adds tenderness to the crumb.
- Molasses
- Adds moisture, dark sweetness and a deep caramel-like flavour.
- Butter
- Adds fat for richness and a tender, moist texture.
- Raisins
- Add chewy pockets of concentrated sweetness throughout the pudding.
The step that matters
Pour the batter into the mold without overfilling. Batter rises as the baking soda reacts and the steam expands the crumb. Leaving headroom in the greased mold lets the pudding rise without spilling or becoming dense.
Swap the allspice
How well each one fits the dish's main ingredients (milk, flour, molasses, butter, raisin):
- Cinnamonfits better
- Nutmegfits better
- Clovefits about as well
- Allspicethe original
Fit is the average pairing score against milk, flour, molasses, butter, raisin. Candidates are from the same food group and used in at least 100 recipes.
