In Biloxi we're getting jumbo shrimp for 3.99/lb. We butterfly them, and the splayed-out end of them sticks out like a little whale-tail. First we fill the popper half-way up with walmart-brand shredded italian blend - it's mozzarella, provolone, parmesan and asiago, sprinkle the whole butterflied shrimp with cajun spices, and stick it in skinny side down. We brush a big glop of melted butter on the whale-tail. We have a popper rack, which you definitely need for the whale-tail weight at the top.
