Luscious Lemon Squares

One day, my dear friend Melissa and I got on the subject of lemon squares. Neither of us had a go-to recipe, so we decided to hit the kitchen and create one of our own. Well, we must have made at least 200 lemon squares. After testing every possible variation, we came up with this be-all and end-all recipe. The squares have a crisp shortbread crust and luscious lemon filling. They’re not too tart and not too sweet—they’re just right.
