Why it works: Flour and lemon are a kitchen classic. They rank in the top 17% of all ingredient pairs, and cooks put them together in 30,404 recipes. Both carry isobutyraldehyde, which smells malty, green. The science ↓
Treacle Pudding
Ingredients
Directions
Make the pastry
Mix the flour, suet, baking powder, and salt in a bowl.
Add cold water to form a stiff paste.
Divide the paste into two equal portions.
Line a pudding basin with one portion of the paste.
Roll out the second portion thinly.
Cut a lid for the pudding from the rolled-out paste.
Fill and seal
Layer treacle, breadcrumbs, and lemon rind in the basin.
Cut a round of rolled-out paste to cover the treacle layer.
Moisten the edges of the paste.
Seal the edges.
Repeat layering with treacle, breadcrumbs, and lemon rind.
Cover with pastry.
Steam
Cover the basin with greased paper.
Steam for 2 to 3 hours.

What each ingredient does
- Flour
- Forms the main structure of the pastry that holds the filling.
- Suet
- Adds fat that keeps the pastry rich and tender as it steams.
- Baking powder
- Releases gas during cooking so the pastry rises and lightens.
- Breadcrumbs
- Soak up the treacle and lend body to the sweet filling.
- Treacle
- Provides sweetness and a dark, rich flavour for the filling.
The step that matters
Seal the edges. Moisten the edges before sealing so the paste bonds; a loose seam lets steam and syrup escape and can leave the filling dry or the pudding collapsed.
