Monthly Challenge: Macaroni and Cheese Soup

The Monthly Challenge for February was to make soup or stew.  I have to ask your forgiveness.  You see, this soup was so delicious that I completely forgot to take a picture!  Everyone in the family gave this a big hooray... doesn't happen that often when we all can agree on a keeper recipe!

Macaroni and Cheese Soup
adapted from Food Network Magazine

Kosher salt
1 cup dry elbow macaroni
1/2 medium onion, chopped fine
2 tablespoons butter
1 carrot, shredded
1 stalk celery, shredded
3/4 teaspoon dry mustard powder
1/8 teaspoon cayenne pepper (we like heat so I added more, but this is a good start!)
1/4 cup all-purpose flour
3 and 3/4 cups chicken stock
1 and 1/4 cups milk
1 cup sharp cheddar cheese, shredded
1/2 cup shredded Mexican cheese blend

Directions:

Fill a large sauce pan with water, add kosher salt and bring to a boil.  Add macaroni and cook according to
package directions.  Drain and set aside.

In a saucepan, add 2 tablespoons butter and melt; add the vegetables and cook over medium high heat until softened, about 4 minutes.  Add the flour; cook stirring constantly for another 2 minutes (you want the flour to brown slightly to eliminate the raw taste of flour).  Add the mustard powder ad cayenne pepper.  Gradually stir in the stock and bring to a boil; stir until thickened, about 6 minutes.
Remove from the heat and add the milk, cheeses and macaroni.  Stir until the cheese melt; season with salt and pepper to taste.
