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 ↓

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 sponge together as it cooks.
- Suet
- Adds fat that keeps the pudding tender and moist.
- Golden syrup
- Adds sweetness, moisture and the characteristic treacle flavour.
- Egg
- Binds the batter and helps give the sponge its set structure.
- Baking powder
- Releases gas during cooking, helping the pudding rise and become light.
- Milk
- Adds moisture and loosens the batter so it mixes evenly.
The step that matters
Mixing in the syrup gradually. Adding the golden syrup a little at a time helps it blend evenly into the flour and suet, so the batter cooks with an even texture and sweetness rather than streaks of syrup.
