Caramel Self Sauce Pudding

This is another wonderful family recipe, the type of recipe that women used to pass around and share with each other. From the family hand written cook book:

1 cup Self Raising Flour
1/2 teaspoon salt
3/4 cup sugar
1/2 cup milk
2 tablespoons melted butter

Mix into batter and spoon into greased oven-proof dish. Sprinkle with 1 cup brown sugar, (and optional 1 teaspoon instant coffee).

Gently pour 1 3/4 cup boiling water over the batter and topping. (I pour over the back of a spoon).

Bake in oven 190C or 375F (a little less for fan forced) for 40 - 45 minutes.
