Add the lemon zest to the granulated sugar, and massage it to release the lemon aroma. Set it aside.
1½ tablespoon Lemon zest, ¾ cup Sugar
Sift all dry ingredients and set aside.
1½ cups All-purpose flour, ½ teaspoon Baking soda, ¼ teaspoon Salt
Beat the softened butter with sugar/ lemon zest mixture for 2-3 minutes until full blended and creamy.
½ cup Butter
Add in the egg and extracts, and mix well.
1 Egg, 1½ teaspoon Vanilla extract, ¼ teaspoon Lemon extract
Add in the lemon juice and food coloring, if using. Mix well.
1½-2 tablespoon Lemon juice, 2-3 Drops Yellow gel food coloring
Add in the dry ingredients and mix until there is no trace of dry ingredients, but do not overmix. Cover the cookies with cling wrap and chill for at least 2 to 4 hours.
When ready to bake, preheat the oven to 350°F. Line the baking sheet with parchment paper.
Make small balls of cookie dough using a scoop. It is up to you how large or small you want the cookies to be. I scooped them into a size of a walnut in the shell.
Set the coating sugars in two separate bowls. Roll each ball into the granulated sugar first, then roll them into the powdered sugar. Make sure they are covered in a generous amount of powdered sugar.
1 cup Granulated sugar, 1 cup Powdered sugar
Place them on the lined baking sheet, and leave a 2-inch space between them. Bake for 9-11 minutes. Mine were ready at 10 minutes.
Leave them on the baking sheet to cool down for 5 minutes, then transfer to the cooling rack to cool down completely.
