Preheat oven to 350°F. Line a baking sheet with parchment paper.

Combine fresh lemon juice, lemon zest, butter, and sugar in a bowl. Beat with a hand mixer until light and fluffy.

Sift flour into the butter mixture and stir to fully combine the ingredients. If desired, add food coloring to tint the cookies to your preferred color.

Use your hands to pack the dough together into two balls, cover in plastic wrap, and refrigerate for 20 minutes.

After the dough chills, place it on a floured work surface and use a rolling pin to roll out the dough to 1/2 inch thickness.

Stamp the dough with your desired cookie-cutter shape and transfer to baking sheet.

Bake the cookies at 350°F for 10-12 minutes, watching the color of the cookies closely, until they just start to turn a light golden color.

Remove the cookies from the oven and let them rest for 2–3 minutes before transferring to a wire cooling rack to cool completely.
