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 ↓
Sponge Pudding
Ingredients
Directions
Make the batter
In a large bowl, mix the suet (or butter) with molasses and milk.
Add flour, eggs, raisins, currants, citron, spices, and baking soda, and stir until well combined.
Steam and serve
Pour the mixture into a greased pudding mold.
Steam for 3 hours.
Serve with wine sauce.

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
- Flour
- Forms the structure that holds the pudding together as it steams.
- Eggs
- Bind the batter and help set the pudding's structure as it cooks.
- Baking soda
- Reacts with the acidic molasses to produce gas that lightens the pudding.
- Molasses
- Adds sweetness, dark color, and moisture with a deep, rich flavor.
- Suet
- Adds fat and richness, keeping the pudding moist and tender as it steams.
The step that matters
Stir until well combined. Thorough mixing spreads the baking soda evenly through the acidic molasses batter so it rises uniformly rather than in pockets.
Swap the currant
How well each one fits the dish's main ingredients (butter, molasses, milk, flour, egg, raisin):
- Vanillafits better
- Figfits better
- Coconutfits about as well
- Currantthe original
Fit is the average pairing score against butter, molasses, milk, flour, egg, raisin. Candidates are from the same food group and used in at least 100 recipes.
