In a small stockpot, heat the oil over medium heat. Saute the artichokes, sausage and onions until lightly colored, about 5 minutes. Add 12 cups (3 quarts) water, the potatoes, crab boil spice mix, salt, hot sauce, pepper, bay leaves and jalapenos. Cover the pot and bring to a boil. Reduce the heat, add the corn and cover. Cook until the corn is tender, about 10 minutes. Add the crab and cook about 7 minutes. Strain the boil through a colander. Plate immediately on a large serving dish. Garnish with sliced green onions or your favorite fresh herb. Serve with the Garlic Bread.
Position an oven rack in the top of the oven and preheat the broiler.
In a small bowl, mix the butter together with the Parmesan, parsley, garlic and scallions; add hot sauce, salt and pepper to taste. Spread the butter mixture on both halves of the baguette. Place on a sheet pan and toast under the broiler, about 2 minutes.
