Mary's Fruit Loaf

Mrs B asked me to put this in.

In memory of Mary MacLeod

Ingredients
4 oz / 100 g soft margarine
1 cupful sugar
3/4 cupful sultanas
3/4 cupful currants or mixed fruit
1 level teaspoon bicarbonate of soda
1 cupful cold water
2 cupfuls self-raising flour
1 egg

Put the margarine, sugar, fruit, bicarb and cold water into a pan and bring to the boil. Simmer gently for 5-8 minutes.
Leave to cool.
Sieve into mixture the self-raising flour and add one beaten egg.
Put this mixture into a 1lb [500 g] loaf tin and bake in gas oven mark 4 / 180 C / 350 F for about an hour. Some times it may be ready a few minutes early; test with a skewer, knitting needle of knife.
Leave in the tin to cool, which makes it easier to cut the next day.
