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 together.
Form into a stiff paste with cold water.
Divide the paste into two equal portions.
Line a pudding basin with one portion.
Cut off enough paste from the other portion to form a lid and roll the remainder out thinly.
Fill and steam
Add a layer of treacle in the basin, sprinkle with breadcrumbs and lemon rind.
Cut a round from the rolled-out paste to cover the treacle, moisten the edges, and join to the basin lining.
Add another layer of treacle, breadcrumbs, and lemon rind, and cover with pastry as before.
Repeat until the basin is full, then cover with greased paper.
Steam for 2.5 hours.

What each ingredient does
- Flour
- Forms the paste that wraps and holds the pudding together.
- Suet
- Adds richness and a tender, crumbly texture to the pastry.
- Baking powder
- Lightens the pastry so it rises slightly as it cooks.
- Treacle
- Provides sweetness and a dark, rich flavour in each layer.
- Breadcrumbs
- Soak up the treacle and keep the filling from becoming soggy.
The step that matters
Joining the pastry lid to the basin lining. If the edges are not moistened and sealed, steam can escape or the filling can leak out during the long steaming, so the pudding may collapse or turn out dry.
