In the house where I grew up, my father, the king of the grill, loved to cook lamb chops more than anything else. In my taste memory, those grilled chops are perfect, juicy and a little bit salty, and I don't want to mess with a perfect memory. Instead, I've adopted boneless butterflied leg of lamb as our house specialty. My local supermarket sells leg of lamb in weights from two to three-plus pounds, already boned and butterflied. The basic marinade begins with yogurt and olive oil, and you can spice it up with any combination of flavorings. After a long languish in a marinade, it goes on the grill for less than 20 minutes. One suggestion: even if you're a lamb whisperer like my dad, use an instant-read thermometer. Overcooked lamb is not wonderful, and on a very hot grill, it's easy to overdo it. Cold leftover grilled lamb, on the other hand, is wonderful, on sandwiches and stuffed into pitas.
