Nothing too exciting. Just a few handfuls of whatever sultanas/currants/mixed fruit I have, a bit of mixed spice and a spoonful of brown sugar.

If I'm feeling fancy enough to use an actual recipe I use a hot cross bun recipe that works nicely for a loaf too:

600g flour ( 4 cups)
1 tsp dry yeast
1 tsp nutmeg
1 tsp cinnamon 1/2 tsp salt
80g caster sugar (1/3 cup)
80g butter - rub into dry ingredients
1 egg, lightly beaten
1 cup milk
1/3 cup water
180g sultanas

Prove, divide, prove & bake

Makes 12. 200 degree oven 15 mins

loaf: 1/2 quantity, 110g fruit, small tin.

I second this.
