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 ↓
Plum Pudding
Ingredients
Directions
The book gives no cooking times; the times in the steps were added in transcription, so check for doneness rather than trusting the clock.
Make the batter
Dissolve the baking soda in the milk.
In a large bowl, combine the chopped suet, molasses, milk, flour, egg, raisins, walnuts, spices, and salt. Mix until well combined.
Steam and serve
Pour the mixture into a greased pudding mold.
Steam for about 2 to 3 hours until cooked through.
Transcribed from a scanned cookbook and modernised for today's kitchens. Where the book gave no heat or time, or said "a moderate oven", the temperatures and times here may be modern equivalents rather than the book's own figures.

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
- Baking soda
- Reacts with the molasses and milk acid to lift and lighten the dense batter.
- Flour
- Provides the structure that holds the pudding together as it sets.
- Egg
- Binds the ingredients and helps set the pudding's structure as it cooks.
- Molasses
- Adds sweetness, dark color, and moisture, and gives a deep flavor.
- Suet
- Adds fat that keeps the pudding moist and rich in texture.
The step that matters
Dissolving the baking soda in the milk. Baking soda needs an acid to react and lift the batter. Dissolving it fully in the milk first spreads it evenly so the pudding rises uniformly rather than in patches.
Swap the walnut
How well each one fits the dish's main ingredients (molasses, milk, flour, egg, raisin):
- Almondfits better
- Chestnutfits better
- Nutsfits about as well
- Walnutthe original
Fit is the average pairing score against molasses, milk, flour, egg, raisin. Candidates are from the same food group and used in at least 100 recipes.
“What each ingredient does” and “The step that matters” were written by Claude from this recipe’s own method and reviewed in samples by CompKitchen.
