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 ↓
A Treacle Pudding
Ingredients
Directions
Make the batter
In a large bowl, mix the suet, flour, treacle, sugar, and lemon juice.
Add enough milk to form a thick batter.
Boil
Tie the mixture in a floured cloth, leaving room for it to swell.
Boil the pudding for three hours.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Suet
- Fat that keeps the pudding moist and tender as it cooks.
- Flour
- Provides the structure that holds the pudding together.
- Treacle
- Adds sweetness, dark colour, and moisture with a rich flavour.
- Lemon juice
- Adds a bright acidity that balances the sweet treacle.
The step that matters
Tying the cloth with room to swell. The mixture expands as it heats, so the cloth must be loose enough for it to rise. If it is tied too tightly, the pudding can become dense or split the cloth.
Swap the lemon
How well each one fits the dish's main ingredients (flour, sugar, milk):

- Lemonthe original
Fit is the average pairing score against flour, sugar, milk. Candidates are from the same food group and used in at least 100 recipes.
