Why it works: Flour and milk are a kitchen classic. They rank in the top 14% of all ingredient pairs, and cooks put them together in 78,219 recipes. Both carry isobutyraldehyde, which smells malty, green. The science ↓
Treacle Pudding
Ingredients
Directions
Prepare the pudding
Boil a large saucepan of water.
Chop ¼ lb of suet finely after removing the skin.
In a bowl, combine 1 lb of flour, ¼ teaspoon salt, and 1 teaspoon baking powder.
Add the chopped suet and 1 teaspoon ground ginger, mixing well.
In another bowl, mix ½ cup treacle, ½ cup milk, and 1 egg.
Stir this mixture into the dry ingredients, adding more milk if needed to achieve a moist but stiff consistency.
Grease a quart basin and pour the mixture into it, ensuring it is full to prevent water from spoiling the pudding.
Sprinkle flour over the top, cover with a cloth, and tie it tightly with string.
Steam and serve
Once the water is boiling, place the pudding in the saucepan and boil for 2 hours.
Remove the pudding from the saucepan, take off the cloth, and serve.

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
- Flour
- Forms the structure of the pudding batter as it steams.
- Suet
- Adds richness and a tender, moist texture as it melts during cooking.
- Baking powder
- Releases gas in the batter to lighten the pudding as it heats.
- Treacle
- Adds sweetness, dark colour and a rich molasses flavour.
- Egg
- Binds the batter and helps give the pudding its set structure.
- Milk
- Adds moisture so the batter reaches a moist but stiff consistency.
The step that matters
Fill the basin completely before steaming. A full basin leaves little air space, so the pudding keeps its shape and water cannot seep in and spoil it during the long boil.
Swap the ginger
How well each one fits the dish's main ingredients (flour, milk, egg):
- Nutmegfits better
- Cinnamonfits better
- Jalapenofits better
- Gingerthe original
Fit is the average pairing score against flour, milk, egg. Candidates are from the same food group and used in at least 100 recipes.
