From 1922:

Sift half a cupful of plain flour with half a teaspoonful of salt, half a teaspoonful of bicarbonate of soda, and one teaspoonful of cream of tartar. Add one cupful of whole meal and one tablespoonful of sugar. Mix well, then add a small half cupful of sultanas. Mix all with milk enough to make moist, but not sloppy, mixture. Put into a billy which has been well greased with lard. Put on the lid, and bake in a quick oven, lowering the heat after 20 minutes till the oven is moderate, and baking for 40 minutes longer.
Lard is more satisfactory than either butter or dripping for greasing cake tins of pudding molds. If lard is used the cakes never stick.
