Ingredients:
- 226g unsalted butter, softened
- 300g granulated sugar
- 2 tbsp fresh lemon zest
- 1 tbsp fresh lemon juice
- 1 large egg, room temperature
- 5ml vanilla extract
- 345g all-purpose flour
- 8g cornstarch
- 5g baking soda
- 2g cream of tartar
- 2g fine sea salt
- 120g powdered sugar, sifted
- 30ml fresh lemon juice (for glaze)
- 1 tsp lemon zest (for garnish)
Instructions:
- Prep the oven. Preheat your oven to 180°C and line two large baking sheets with parchment paper.
- Infuse the sugar. In a small bowl, combine 300g granulated sugar and 2 tbsp fresh lemon zest. Use your fingers to rub the zest into the sugar until the sugar looks damp and smells intensely fragrant.
- Cream the fats. Beat 226g softened butter and the lemon infused sugar in a stand mixer until the mixture is pale and fluffy. This usually takes 3 to 5 minutes on medium high speed.
- Emulsify the liquids. Add 1 large egg, 1 tbsp fresh lemon juice, and 5ml vanilla extract. Beat until completely combined and velvety.
- Whisk the dry. In a separate bowl, whisk together 345g flour, 8g cornstarch, 5g baking soda, 2g cream of tartar, and 2g fine sea salt.
- Combine the dough. Slowly add the dry ingredients to the wet. Mix on low until just a few streaks of flour remain, then finish by hand with a spatula.
- Scoop and roll. Form 2 tablespoon sized balls of dough. Place them on the trays, leaving 5 cm of space between them. Do not flatten them.
- Bake the batch. Bake for 9 to 11 minutes until the edges are set and the tops have lost their shine.
- Cool properly. Let the cookies sit on the hot pan for 5 minutes, then move them to a wire rack until they are completely cool to the touch.
- Glaze and finish. Whisk 120g powdered sugar with 30ml lemon juice. Drizzle over the cooled cookies and sprinkle with 1 tsp extra zest until the glaze shatters when bitten.
