Preheat oven to 350⁰F (175⁰C). Prepare 9″ x 5″ loaf pan.
Stir together flour, baking powder, salt and nuts.
In a large bowl, beat together margarine and 1 cup of sugar. Beat in eggs one at a time.
Stir in rind and 1/2 cup juice.
Pour into the flour mixture and stir until moistened.
Turn into prepared loaf pan. Bake for 1 hour or until done. Remove from oven but not from pan.
Combine 1/2 cup juice with 1/4 cup sugar in a small saucepan. Heat and stir to dissolve sugar. Spoon glaze over hot loaf. Let stand in pan for 10 minutes before removing loaf to rack to cool.
BAKING TIP: Nut breads are best stored overnight before cutting. The flavours mellow and the loaves are easier to slice.
