Start by preheating your oven to 350 degrees F and grease or line a 6x5 inch loaf pan.
In a large bowl, mix together 2 cups of all purpose flour, 2 tsp baking soda, 1 cup sugar, and 1 tsp salt. Cut in butter.
Break the egg in a measuring cup and fill to the 1 cup line with milk.
Add liquid to dry ingredients and mix thoroughly. Add 1tsp vanilla extract and 2tsp lemon juice (taste batter to decide if it needs more lemon juice or not)
Pour batter into your lined pan and bake. The recipe said to bake it for 30 minutes, but I found that it took at least 45 minutes.
It turned out delicious and perfectly moist. Next time I think I will use a little more lemon juice because the lemon is more noticeable in the aftertaste.
