We are in Puerto Vallarta this week, able to partake in one of my personal indulgences. Ceviche. It's raw fish, or shrimp, 'cooked' in lime juice. With onion, tomato, cilantro, jalapeno, cumin, salt. The seafood turns opaque when 'done'. Spoon (or scoop) on crisp tostadas with spicy salsa. Delicioso!
