        1. Oh sorry Molly. :) I haven’t tried doubling this in a 9×13 pan so I can’t say for sure. You could certainly double it into two 9×9 pans.

    1. I am sure you could do that Elda, make sure to not overfill the pan, and you may need to use 2 pans depending upon the size of your loaf pan!

  1. Do you leave the lime zest in long strips, from the zester, or do you chop them up a bit? Wouldn’t it be easier to use a microplane, or the small holes on a grater, to get tiny pieces of the lime zest?
