Pour 3 cups of water into the bottom of a steamer pot (steamer pot should have a basket or tray to keep the ingredients out of the water). You will need an 8-quart or larger steamer. Layer the potatoes, corn and smoked sausage in the basket. Sprinkle with about 1 tablespoon Old Bay Seasoning. Spread the crab over the clams and sprinkle with Old Bay. (NOTE: you cannot use too much Old Bay.) Cover the pot and place over high heat until it starts to boil, reduce the heat to medium and let steam for 20 to 25 minutes.
Dump the contents of the pot, but not the water, onto a large platter and serve with melted butter.Makes 4 Source:
