In a large bowl, cream together the shortening and sugar, mixing well.
Add the eggs and beat well again.
In another bowl, mix together 1 cup of the flour, baking powder, and salt and then add that mixture to the creamed mixture, blending well to incorporate.
Next, blend in the milk, lemon juice, lemon rind, and walnuts.
Add the remaining 1 cup of flour and mix well again.
Pour the batter into a well-greased loaf pan and bake for 90 minutes.
For glaze: Mix together the sugar, lemon rind, and lemon juice.
(You may need a few more drops of lemon juice if the mixture is too thick.
) When the bread is done, spread the glaze on top of the loaf and let cool.
