Preheat oven to 350°F and prepare a 9 inch loaf pan
Combine flour and salt and whisk together to remove any lumps and set aside
Add butter and sugar to mixing bowl and mix on med-high speed until light and fluffy about 5 mins.
Add eggs one at a time and beat well after each, then add lemon zest and juice.
Gradually add flour and salt mixture until combined without over mixing
Spoon into prepared loaf pan and bake uncovered for 55 mins. Then loosely cover and bake for another 10-15 mins until inserted tooth pick comes out clean with few crumbs.
