To get a really good flavor you must use real keylimes. It’s a bit of a hassle prossesing those tiny little limes, but it’s worth it in the end. You will also need real keylime juice, which you can find at the supermarket. The limes just don’t have enough juice by themselves. Zest your limes first because you will need zest for the crust and the batter.
This recipe is a combination of several recipes, I just pulled what I liked from each one to come up with this recipe.
