  • *citric acid (also known as sour salt) is what gives the cookies their sour bite—if you want less tang, use just a pinch.
  • In a medium-sized bowl, beat together the butter, sugar, salt, and baking powder till well blended.
  • Beat in the lime juice, lime oil, sour salt (citric acid), and the egg.
  • Blend in the flour thoroughly.
  • Roll the dough into 1" balls, and place them on lightly greased or parchment-lined baking sheets.
  • Bake the cookies in the top third of a preheated 350°F oven for 14 to 16 minutes, until the cookies are browned on the bottom.
  • Remove them from the oven, and cool on the pan for about 10 minutes before transferring to a rack.
  • Mix together the sugar coating ingredients in a pan or bag.
  • Gently shake and roll the still slightly warm cookies in the sugar till coated. Allow the cookies to cool completely, then repeat, coating again with the sugar.
  • (If you're freezing the cookies, you may choose to recoat the cookies in sugar once they've been removed from the freezer, before serving.).
