The lobsters are boiled in a mixture of water, fresh lime juice, salt, scallions, parsley, garlic, and a small piece of hot pepper. The dipping sauce is made with butter, scallions, oil, fresh ground pepper, salt, and champagne vinegar. To finish, just your hands and an empty stomach are needed.
In a large pot of boiling water, add lobsters, salt, parsley, scallions and lime juice. Cook the lobsters, covered, until done, about 10 minutes after the water returns to a boil.
Meanwhile, in a medium saucepan, melt butter, add scallions and hot pepper if using. Let cook for about 1 - 2 minutes while stirring. Add champagne vinegar and black pepper and let cook for an additional 1 - 2 minutes. Remove the pan from the heat and serve sauce with lobsters as a dipping sauce.
