When the weather gets cold, there is nothing like a rich soup to warm you up. My friend Meredith once commented sautéing onions is the best cooking smell there is. This soup takes that to a whole new level, and the leeks are the star. The leeks are roasted to add smokiness and the onions and shallots are sautéed with butter. Then some vermouth and heavy cream gets introduced and everything comes together.
