Put steamers or quahogs in the bottom of a large pot with 2 inches of water.
Then layer white and sweet potatoes, hot dogs, sausages, chourico, onions, eggs and a good size onion placed right on top.
Mix 1 tablespoon crushed hot peppers with 1/2 cup water and pour allowing mixture to filter through the boil.
Cover pot with lid and bring to a boil and then lower heat and let it steam.
When the large onion place right on top is cooked - so is the boil, approximately 1 1/2 hours.
Serve with melted butter and broth from the boil for dipping clams. ENJOY!
