Place a piece of buttered bread, butter side up, on top of the cheese.
Add the pork mojo in the same manner.
Place the last slice of bread on top of the sandwich, butter side down.
Neatly trim the crusts, cut in half on the diagonal, and pack neatly away between parchment sheets.
Carefully batter each half of the sandwich individually. Allow to sit in batter to fully soak in.
Add a small ladle of clarified butter to a hot cast iron pan and carefully toast each side of the bread. Do not flip until a full golden crust has formed.
Remove the sandwich from the pan and fry at 350 degrees until it is golden brown and the cheese inside is fully melted.
Remove from oil and drain well.
