Sauté the carrots, onion, dill, and celery in the butter in a large saucepan. Sprinkle in the flour 1 tablespoon at a time, stirring after each addition.
Add the stock. Bring to a boil over medium heat, and cook for about 5 minutes. Strain out the vegetables, purée them in a food processor fitted with a steel blade, then return the puréed vegetables to the stock. Continue to cook over medium heat until the soup boils, then reduce the heat and let it simmer slowly for 15 minutes. Add the grated cheese, stirring constantly with a large wire whisk until it is melted. Slowly add the half-and-half and stir until well blended. Add the salt and pepper to taste. Serve at once garnished with the toasted sesame seeds.

"I saw lots of recipe software for PC computers but I was having a hard time finding really good mac recipe software. I'm so glad I discovered Cook'n! It's so nice to have all my recipes in a computer recipe organizer. Cook'n has saved me so much time with meal planning and the recipe nutrition calculator is amazing!!!
My favorite is the Cook'n Recipe App.
