In a small saucepan, gently melt the unsalted butter over low heat, then set aside to cool slightly.

In a large mixing bowl, combine the "00" flour, granulated sugar, baking powder, and fine sea salt, mixing well to distribute.

Create a well in the center of the dry ingredients. Add the large eggs, the cooled melted unsalted butter, and the lemon zest into the well.
