Preheat the oven to 180oC/350oF/Gas 4.
Then line a 23 x 13cm/9 x 5in loaf tin with greaseproof paper and grease
the paper.
Sift the flour, sugar, baking powder
and salt into the mixing bowl. Then stir in the orange rind. Make a well
in the centre and add the fresh orange juice, eggs and melted butter or
margarine.
Stir from the centre until the
ingredients are blended, do not over mix. Add the berries and walnuts
and stir until blended.
Transfer the mixture to a prepared
tine and bake until a skewer inserted in the centre of the loaf comes
out clean, about 45 - 50 minutes. Leave to cool in the tin for 10
minutes before transferring to a wire rack to cool completely.
