From lemon, grate 1 tablespoon peel and squeeze 4.5 teaspoons lemon juice; set aside. In large bowl with fork, mix flour, baking powder, salt and 1.5 cups sugar. Cut in butter until mixture resembles coarse crumbs. Stir in peel. In small bowl with fork, beat eggs slightly and stir in milk; then stir this mixture into flour mixture just until flour is moistened. Spoon into greased loaf pan. Bake at 180ºC for 1.25 hours. Cool in pan on wire rack 10 minutes; remove from pan. Heat lemon juice over medium-high heat, stirring in 2 tablespoons sugar. Heat to boiling. Cook, stirring, until slightly thickened, about 5 minutes. With pastry brush, brush sugar mixture evenly over top of bread. Serve warm, or cool loaf completely to serve later. I've also made 3 small (3.5x6 inch) loaves with this recipe, baked at 180ºC for 45 minutes.
