Boil together the sugar, sultanas, milk, and butter for five minutes stiring all the time, until the mixture is syrupy and then allow to cool.

When liquid is cooled, add self raising flour (add slowly and mix carefully to avoid lumps)

Stir in the beaten egg

Bake in loaf tin at 325F (165 C (fan)) / 180C ordinary oven for about an hour.

Check after 55 minutes with a skewer to see if it is done (the skewer should come out clean with no sticky cake mixture on it)
