When preparing the dough, it's helpful to designate one hand for dough-making and the other for using the bench scraper. Your dominant hand will primarily focus on making the dough, providing a great workout for your arm muscles.
Begin by placing the butter on your clean workspace. Using the heel of your hand, press down on the butter, pushing it away from yourself. Then, bring the butter back towards you and repeat this motion. Periodically, use the bench scraper to gather any excess butter from the workspace and reincorporate it with the rest.
Continue this process until the butter takes on a slightly lighter shade, indicating that it's been thoroughly worked into the dough. If you'd like a visual reference, feel free to consult the accompanying video for a detailed demonstration of each step.
Now, it's time to incorporate the sugar into the butter. Add the sugar to the butter on your workspace, then repeat the rubbing motion of pushing the butter and sugar down and away from yourself, just as you did with the butter alone.
Keep at it until all the sugar is fully dissolved into the butter, and the mixture achieves a smooth, "salve-like" consistency. This may take a bit of elbow grease, but the end result will be well worth the effort.
Next, it's time to add the lemon zest and salt to the mixture. Incorporate them into the butter and sugar using the same rubbing technique as before. Push the mixture down and away from yourself, ensuring the lemon zest and salt are evenly distributed throughout. This method ensures that every bit of flavor is infused into the dough, creating a deliciously fragrant and well-seasoned base for your cookies.
Now, it's time to add the beaten egg to the mixture. Using the same technique as before, gently incorporate the egg into the mixture. Use the rubbing motion to blend the egg with the butter, sugar, lemon zest, and salt until everything is thoroughly combined. This ensures that the egg is evenly distributed throughout the dough, resulting in a cohesive mixture.
Now, add one-third of the flour to the butter mixture. Using the same rubbing technique as before, gently mix in the flour. Be careful not to overwork the dough. Once the first portion of flour is thoroughly mixed in, add the second portion and repeat the process. Finally, add the last portion of flour and incorporate it into the mixture. This gradual addition of flour ensures that it is evenly distributed throughout the dough, resulting in a smooth and cohesive texture without overworking it.
Your dough should appear pale and feel smooth to the touch, resembling the texture of a salve. While you may still detect some granules of salt, the overall consistency should be cohesive and velvety.
Now, using a bench scraper, make one big heap of dough.
