Seafood Boil

In a large stock pot over medium heat, heat oil until shimmering. Add sausage and cook, cut sides down, until golden on both ends, 2 to 3 minutes a side. Transfer sausage to a plate. Add onion and garlic cloves to pot and let cook, undisturbed, until they begin to brown, 3 to 4 minutes. Add water and, using a wooden spoon, scrape up any brown bits from the bottom of the pot. Add beer, vinegar, Old Bay, bay leaves, salt, sugar, and pepper and bring to a boil. Add potatoes, cover, and cook until mostly tender (a fork should slide in with a little resistance), about 8 minutes. Add corn and clams, cover, and cook 5 minutes more, until most clams are open and corn is bright yellow. Add shrimp and sausage, cover, and cook until shrimp is pink and opaque and sausage is warmed through, 1 to 2 minutes. Drain cooking liquid and discard onion, bay leaves, and any unopened clams. Transfer seafood, potatoes, sausage and corn to serving bowls or a newspaper-lined table. Serve with melted butter, lemons, more Old Bay, and plenty of napkins.
