Preheat oven to 350 degrees Fahrenheit. Line a cookie sheet with Gefen Parchment Paper.

In the bowl of an electric mixer using the cookie paddle (or in a large bowl by hand), cream together butter/margarine and sugar until light and fluffy. Add egg, lemon juice, lemon zest, and mint and mix well. Add dry ingredients and mix well.

Form dough into a ball and flatten into a disc shape. Refrigerate for at least 30 minutes.

Roll to approximately quarter-inch thickness and cut shapes. Place on cookie sheet.

Bake for 11 minutes. For soft cookies, do not overbake. For crispier cookies, bake for an additional one to two minutes.
