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 ↓
Christmas Pudding
Ingredients
Directions
Make the batter
In a large bowl, combine the suet, raisins, sugar, flour, bread crumbs, milk, eggs, and spices.
If using sweet milk, add baking powder; if using sour milk, add baking soda. Mix well until all ingredients are combined.
Steam and serve
Pour the mixture into a greased pudding mold.
Steam for three hours.
Serve with a sauce of your choice.

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.

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
- Eggs
- Bind the batter and add structure as the pudding sets.
- Flour
- Provides the main structure once the pudding is steamed and set.
- Suet
- Adds fat that keeps the pudding moist and rich in texture.
- Baking powder or baking soda
- Releases gas that helps the pudding rise and become light.
- Bread crumbs
- Absorb liquid and add body to the batter.
The step that matters
Adding the leavener to the batter. Baking powder or baking soda must match the milk: sweet milk needs baking powder and sour milk needs baking soda, because baking soda needs an acid to react. Using the wrong one can leave the pudding flat or give it an off taste.
Swap the raisin
How well each one fits the dish's main ingredients (sugar, flour, bread, milk, egg):
- Vanillafits about as well
- Raisinthe original
- Figfits less well
- Datesfits less well
Fit is the average pairing score against sugar, flour, bread, milk, egg. Candidates are from the same food group and used in at least 100 recipes.
