Ginger cake (1 colour)

This is an old family favourite and I can't remember ever having a Christmas without it.

Ingredients
Golden syrup - 55 g
Black treacle - 170 g
Margarine - 115 g
Brown sugar - 55 g
Milk - 140 ml
Eggs - 2, beaten
Plain flour - 225 g
Bicarbonate of soda - 1 level tsp
Ground ginger - 2 level tsp
Mixed spice - 1 rounded tsp
Sultanas - 115 g

Methods
1) Heat the treacle, syrup, margarine and sugar in a small pan until the sugar and margarine have dissolved. Add the milk and leave to cool for a few minutes.
2) Meanwhile, sift the flour, ginger, mixed spice and bicarbonate of soda into a large bowl.
3) Add the eggs to the cooled treacle mixture and stir well. Pour into the bowl containing the dry ingredients and fold in the sultanas, mixing until everything is well combined. Bake in a greased tin for 1.25 - 1.5 hours at 150°C until a skewer comes out clean. Serves 12.
