Preheat oven to 350 degrees Fahrenheit (180 degrees Celsius). Place oven rack in the center of the oven. Line a baking sheet with Gefen Parchment Paper.

In the bowl of your electric mixer beat the butter and sugar until light in color and fluffy. Beat in the egg, lemon juice, zest, and vanilla extract. 

In a separate bowl, whisk together the flour and salt. Gradually add the dry ingredients to the wet creamed mixture and beat until incorporated.

Fill a piping bag with dough.  Using the piping bag and star tube piping tip, pipe out various shapes of cookies, including stars, horseshoes, shells, rosettes or sticks. Place the cookies on the baking sheet, spacing about 2 inches (5 cm) apart.

If you like, make an egg wash by beating one egg white with 1 teaspoon water. Brush cookies with the egg wash.

Optional: sprinkle with chopped nuts, rock sugar or colored sugar before baking.

Bake the cookies for about 10–15 minutes, or until the edges of the cookies are golden brown. Remove from oven and place on a wire rack to cool. 

You can dip the cooled cookies in melted chocolate and roll in sprinkles.
