Treacle Sponge

Ingredients

Directions

The book gives no cooking times; the times in the steps were added in transcription, so check for doneness rather than trusting the clock.

Prepare

  1. In a bowl, combine bread crumbs, suet, salt, egg, and baking powder. Mix well until all ingredients are combined.

  2. Pour the mixture into a greased steaming dish.

Steam and serve

  1. Steam for about 1 hour until cooked through.

  2. Once done, pour golden syrup over the sponge as a sauce before serving.

What each ingredient does

Egg
Binds the crumbs and suet together and adds structure to the sponge.
Baking powder
Releases gas as it heats, helping the sponge rise and turn light.
Bread crumbs
Form the bulk of the sponge and give it a soft, absorbent body.
Suet
Adds fat that keeps the sponge moist and tender as it steams.
Golden syrup
Adds sweetness and a rich, moist flavour as a sauce over the sponge.

The step that matters

Steaming the sponge. Steam gently and keep the water topping up so the sponge cooks through evenly. Too little heat or water leaves the centre dense and underbaked, while the baking powder needs steady heat to lift the batter.
