According to The Florida Keys Cookbook, where I found this recipe, the Bahamians held the conch in mystical regard, believing its consumption enhanced male potency. They brought the recipe with them when they immigrated to the Florida Keys.
Place olive oil, onions, bell peppers, ham and garlic in a large soup pot over medium high heat. Saute, stirring occasionally, for 5 minutes or until onion is translucent. Add tomatoes, tomato paste, tomato juice, hot water, bay leaf, barbecue sauce, marjoram, sage, thyme, parsley, oregano, salt, cracked and cayenne peppers. Stir to combine ingredients and bring mixture to a boil.
Add conch to the pot. Reduce heat to low and simmer, covered, for 5 to 6 hours or until conch is tender. Lace each individual serving with hot pepper sherry to taste.
