Inspired by jiao yan xia, the classic Chinese dish of head-on, fried shrimp finished with a Sichuan or white pepper salt seasoning, these shrimp rolls celebrate the flavors of salt and pepper. Peeled shrimp are seasoned, breaded with cornstarch and fried until super crunchy, then sprinkled with a black pepper-salt. Once cooked, they’re tucked into toasted rolls smeared with a zingy garlic mayo. Fresh cilantro, sliced chile and a squeeze of fresh lime brighten the hearty sandwich. Store any leftover pepper-salt in an airtight container and use it as a seasoning for roasted meats and vegetables.
