Rinse and spit clams in cold running water. Drain and set aside.
Heat the pan and add the oil. Add the clams and sauté for a minute or two. Add the garlic and cook out, then add the water and cover to steam open.
Add the pepper, Oyster-flavored sauce, sugar, and soy. Finish with butter, the cilantro, and a squeeze of fresh lime. Plate and top with the fresh herb mix.
