Meanwhile, melt the clarified butter in a skillet over medium heat. Stir in 2 tablespoons of garlic, and cook until golden, about 2 minutes. Add the leeks, and cook 1 minute more. Stir in the morel mushrooms, oyster mushrooms, chanterelle mushrooms, tomatoes, and Creole seasoning; cook and stir until the mushrooms begin to release their liquid, about 3 minutes. Pour in the cognac and simmer 2 minutes before pouring in the shrimp stock and veal stock. Return to a simmer, and cook until the liquid has reduced by half. Stir in the shrimp, thyme, and 3 tablespoons of butter. Cook and stir over low heat until the shrimp is no longer translucent, about 4 minutes; season to taste with salt and pepper.
