This recipe makes 1 larger cornbread calzone, or up to 3 smaller ones, depending on the size of your cast iron skillets.
Put the skillets in the oven on a baking sheet and set it to 425 to preheat.
Mix the flour, cornmeal, baking powder, and baking soda in a bowl and add salt. Stir to combine
Mix the buttermilk, butter, eggs, jalapeno juice, and honey in a measuring cup and stir well.
Pour the wet ingredients into the dry and mix until combined.
Remove the skillets from the oven and spray with nonstick spray.
Pour in some of the cornbread batter, then add cheese, sausage, jalapenos, and more cheese. Press the mixture to help it sink into the cornbread. Cover with more cornbread batter.
Return the pan to the oven and cook for about 17 - 20 minutes, depending on the size of your skillets. The breads are done when they are starting to brown on top and feel firm to the touch.
To serve, first run a knife around the outside of the pan to loosen the edges, then flip the calzone out onto a plate. Top with butter and honey and serve.
