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 ↓

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
- Provides the structure that holds the pudding together as it steams.
- Baking soda
- Reacts to lighten the batter so the pudding rises and turns spongy.
- Egg
- Binds the batter and adds structure and richness to the crumb.
- Treacle
- Adds sweetness, moisture and a deep caramel flavor to the sponge.
- Milk
- Hydrates the flour and gives the batter its pourable, moist texture.
The step that matters
Steam for 2 hours. Steaming must stay gentle and continuous so the batter cooks through evenly and stays moist. Letting the water boil dry or drop too low can leave the sponge dense or undercooked.
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.
