Aspen, Colorado is quite chilly this time of year, so what could be better than a free festival offering samples of dozens of unique and delicious soups. Watch for tips and tricks from Aspen's finest chefs and of course the award-winning recipe. Our favorites: If your soup's too thin or watery, add a thickener like fresh bread crumbs or mashed potatoes. Is it too thick? Add chicken broth or chicken stock. Other chef secrets: "Don't be afraid of spice," like cayenne pepper. One of the tastiest recipes used duck stock, which has a thicker and richer flavor than most other stocks.
