- Prep. Preheat oven to 350℉. Generously spray a 9x5 or 8x4 loaf pan with nonstick spray and set aside. 
- Beat sugar and shortening. In a large mixing bowl, beat the shortening and sugar until light and fluffy. 
- Add eggs. Add the eggs one at a time, beating well after adding each one. 
- Mix dry ingredients. In a separate bowl, whisk together the flour, baking powder, and salt. 
- Combine mixtures. Slowly add the dry ingredients to the sugar mix, alternating with the milk. Stir until just mixed. 
- Add lemon. Add the lemon zest and juice.  Use a spatula to make sure everything is well incorporated. 
- Bake. Put the batter into the loaf pan you prepared. Bake for 50-60 minutes or until a toothpick inserted into the center comes out clean. Let the bread cool in the pan for 10 minutes, then move it to a wire rack to cool completely. 
- Make the glaze. While the bread is cooling, prepare the glaze. Mix the powdered sugar, lemon zest, and lemon juice in a small bowl until smooth. Once the bread is slightly cooled but still warm, drizzle the glaze over the top. Let the bread cool completely before slicing and serving. 
- Cool. Allow the bread to cool down completely in the pan before removing and serving.
