Cheddar Soup

This is one of my Mom's favorites and a favorite at the tea room that she and my sister used to own. Its creamy and so good!

Ingredients to serve 8
1/4 cup of butter or margarine
1/2 cup finely chopped onion
1/2 cup finely chopped carrots
1/2 cup finely chopped celery
1/4 cup flour
1 and 1/2 tablespoons cornstarch
1 quart chicken broth
1 quart half and half
1/8 teaspoon baking soda
2 and 1/2 cups grated cheddar cheese
salt and pepper to taste

Melt the butter in a heavy sauce pan over medium heat. Saute in the melted butter, the onion, carrots, and celery (I chop these in a food processor) Saute until soft.Gradually stir in the flour and cornstarch.Reduce heat to low and gradually stir in the chicken broth and half and half. Continue cooking and stirring until thickened and smooth.Stir in the baking soda and grated cheddar.Stir until cheese is melted.Add salt and pepper.Enjoy!Note: Be sure to use half and half, not milk.When you add the flour and cornstarch to make the roux, it will quickly thicken, so be sure to stir.

Variations: crumble bacon bits on top or mix with a potatoe soup.
