01 - Preheat oven to 350°F. Grease and line a 2-pound loaf pan with parchment paper.
02 - In a large bowl, cream butter and caster sugar until pale and fluffy.
03 - Beat in eggs one at a time, mixing thoroughly between additions.
04 - Fold in self-raising flour, salt, and lemon zest gently until combined. Stir in milk.
05 - Pour batter into the prepared loaf pan and smooth the surface.
06 - Bake for 45 to 50 minutes until a skewer inserted into the center comes out clean.
07 - While baking, combine lemon juice and granulated sugar until sugar dissolves.
08 - Remove cake from oven. While still in the pan, prick the surface with a skewer and pour drizzle evenly over the top.
09 - Allow cake to cool completely in the pan so the drizzle soaks in. Remove, slice into 10 pieces, and serve.
