Self saucing plum pudding

The neighbours gave us a big bag of plums so we decided on two recipes :

2 cups self raising flour
Pinch salt
50 g butter (soft)
1/4 cup sugar
1 egg
1 tsp vanilla essence
1 cup milk
Plums - pips removed
100g fruit jam - plum, strawberry ...

Preheat oven to 180 degrees C.
Sift flour and salt into a bowl.
Add the sugar.
Stir in the butter.
Stir in egg, milk and vanilla essence.
Place plums at bottom of oven proof dish.
Pour batter over.
Mix the jam and boiling water and gently pour over the batter using the back of a spoon.
Bake for 40 minutes or until pudding is golden and risen.
Serve with cream or ice cream.
