It's a Delia recipe from her early Book of Cakes which is invaluable.I use a loaf tin(skyline 2lb size and a liner that you buy in Lakeland,so much easier!)Please forgive imperial measurements but I have already halved the recipe to make just one loaf of this size!!
6oz plain flour
3oz butter
1 level tsp ground ginger
1 level tsp cinnamon
generous grating of nutmeg(1/16)
1/2(half) levelteaspoon bicarb of soda
2 tablsp milk
3oz black treacle
3oz golden syrup
3oz soft dk brwn sugar
1 egg,lightly beaten

Sift flour and spices into a large bowl
Mix bicarb with milk and put to one side
Measure treacle, syrup,sugar and butter in to a saucepan
with 75ml of WATER.
Heat gently until melted and blended. DO NOT BOIL OR GO ON FORUM !!!!!
Add this mixture to flour and spices and add egg,bit at a time until well mixed and smooth.Beat with wooden spoon.
Add bicarb and milk mixture.
Pour in to tin.
It takes 50 mins or so.It says 170 C for oven.
Should rise well and be firm to touch,like sponge cakes.
Supposed to leave for 24hrs.Can spread with butter but is fine without!!
