I did some ginormous (4-6 ct) prawns on sale at Fresh Market for $15/# tonight, and they were outstanding. Very similar to lobster.
I've found a couple of tricks:
- leave the shells ON when grilling. They are already deveined and split at the store
- open the shells and pour your marinade inside
- if using lemon, don't let them marinade for more than an hour or so, or the citric acid will "cook" the meat
- grill med-hot and direct, less time than you think. If you even think they *might* be done, they are. These were HUGE, and they spent maybe 5 minutes over a 400-425 fire.
Apologies for the lack of pics. I would highly recommend picking some up at this price if you have a FM nearby.
