Why it works: Flour and butter are a kitchen classic. They rank in the top 12% of all ingredient pairs, and cooks put them together in 124,287 recipes. Both carry isobutyraldehyde, which smells malty, green. The science ↓
Treacle Pudding
Ingredients
Directions
Prepare the crust
Make a crust with suet or dripping and roll it out thin.
Line a basin with the crust and cut eight to ten pieces the size of the basin.
Fill the basin
Grate the rind of the lemon and mix it with the juice and treacle.
Pour a little treacle mixture on the crust in the basin.
Place one piece of crust over the treacle, then add more treacle and crust, repeating until the basin is full.
Boil and serve
Tie a floured cloth over the basin and boil for one and a half hours.
Serve with melted butter and additional treacle.

Flour and butter barely smell alike, yet cooks put them together in 124,287 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
- Suet or dripping
- Forms a rich, short crust that holds the pudding together and adds fat.
- Treacle
- Provides the sweet, dark, sticky filling that soaks into the layers of crust.
- Lemon
- Its zest and juice add aroma and a bright acidity that balances the sweetness of the treacle.
The step that matters
Tie a floured cloth over the basin. A floured cloth lets the pudding's surface form a dry skin without sticking, and a snug seal keeps boiling water out so the pudding steams rather than becomes waterlogged.
Swap the lemon
How well each one fits the dish's main ingredients (flour, butter):
- Raisinfits better
- Vanillafits better
- Coconutfits better
- Lemonthe original
Fit is the average pairing score against flour, butter. Candidates are from the same food group and used in at least 100 recipes.
