    What if you can’t find key limes in my part of the world? Can you substitute regular limes? Also, have you ever tried these with lemons?

      Hi Lisa,
      Yes, you can substitute other citrus in place of the key limes to make it any other type of citrus shortbread cookie. I hope you enjoy it!

    SO GOOD!! I used white whole wheat flour, so I can only imagine how even more delectable they are with APF. These are just SO GOOD. I am a bit crazy for citrus & lime is my favorite.
