1.) Shrimp – It’s been the No. 1 seafood in the United States for more than 10 years now, so naturally it’s a favorite for grilling among Americans. “Shrimp is always right there up at the top,” Seaver said. He likes wild Gulf head-on, grilled in the shell. It adds flavor to the shrimp, and makes it easy to prevent sticking. Smaller ones should be skewered, but otherwise they’re a low-stress choice, surely a reason they are so popular in the summer.
