heat your oven to 200 degrees. take a casserole pot, cover the base to a one inch depth with sea salt. let the oven heat up to temperature; put the lid on the pot and stick it in the oven for 30 minutes.
after 30 minutes, take pot out, take the lid off and lay your raw tigers on the salt. put the back lid on & leave for 3 to 4 minutes. no need to put it back in the oven.
take off lid - ta-da! baked tiger prawns with a hint of the sea. serve with melted butter & milled black pepper.
