Jalapeño Cornbread

This is from my sister-in-law, Jane Ricker. I had my first jalapeno upon moving to Texas and never looked back!  Jane says don't dare put this into anything except a cast iron skillet.  I have to confess that I've cooked it in regular pans with great success - just not as crispy.
