Take the butter, cut into thirds, and melt in a large saucepan over medium heat until melted. Next, add the green onions, Worcestershire sauce, crab boil, cayenne, red pepper flakes, salt, black pepper, thyme, garlic, bay leaves and 5 to 6 shakes hot sauce.
Cut the lemon in half, squeeze the juice in and then drop the lemon halves into the pan. Bring to a boil, but there should be no smoke.
Add the shrimp in flat rows on top. Cook until pink, about 2 minutes per side.
