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 ↓
Plum Pudding
Ingredients
Directions
Prepare the batter
Combine suet, molasses, milk, raisins, currants, citron, and eggs in a large bowl.
Mix flour, spices, salt, baking powder, and baking soda in another bowl.
Gradually add the dry ingredients to the wet mixture, stirring until well combined.
Steam and serve
Pour the mixture into a greased pudding mold.
Steam for 4 to 5 hours.

The pairs that carry this dish. Each one is judged two ways: how much their aromas overlap, and how often cooks already put them together.

Shared aroma: decanoic acid (acides aroma).
Milk and flour 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
- Suet
- Adds fat that keeps the pudding moist and rich in texture.
- Molasses
- Adds sweetness, dark color and a deep flavor with some moisture.
- Eggs
- Bind the batter and add structure as the pudding sets.
- Flour
- Provides the main structure that holds the pudding together.
- Baking powder
- Releases gas to lighten the batter and help it rise.
- Baking soda
- Reacts with the molasses acidity to help the pudding rise and darken.
The step that matters
Gradually add the dry ingredients to the wet mixture. Adding flour in stages and stirring until combined prevents lumps and overmixing. Overmixing develops gluten, which can make the pudding dense and tough.
Swap the currant
How well each one fits the dish's main ingredients (molasses, milk, raisin, egg, flour):
- Vanillafits better
- Figfits better
- Datesfits better
- Currantthe original
Fit is the average pairing score against molasses, milk, raisin, egg, flour. Candidates are from the same food group and used in at least 100 recipes.
