Step 1

In a bowl, combine the flour, baking powder, and salt. Set aside.

Step 2

In another bowl, beat the eggs, sugar, and lemon zest with an electric mixer for about 5 minutes or until the mixture forms a ribbon when the beater is lifted.

Step 3

With a whisk, gently fold in the dry ingredients. Fold the butter in the same way. Cover and refrigerate for at least 30 minutes.

Step 4

With the rack in the middle position, preheat the oven to 200 °C (400 °F). Butter and flour a small madeleine pan. Set aside.

Step 5

Fill each cavity three-quarter up with batter. Bake for 8 to 10 minutes or until the madelienes are lightly golden brown. Remove from the pan and let cool completely on a wire rack. Repeat with the remaining of the batter. If desired, serve with lemon curd.
