One of my favorite foods on Earth, I rejoice when lobster season begins and have already cooked the sea beasts twice this summer. Once by boiling and once by grilling–which was slightly more disturbing.
The flavor difference was not very great, I guess I somehow expected a smokiness to the grilled lobster, but it was just less wet and therefore less messy. All you need on top of the basic cook times (roughly 13 minutes for boiling; till it turns red on each side for grilling) is a dish of melted butter. Happy Summer eating!
