Cheesy Catfish Chowder

In a Dutch oven over medium heat, melt butter and saute the onion until tender. Pour in chicken broth and water. Mix in celery, carrots, and potatoes. Cook 10 minutes, stirring occasionally, until vegetables are tender.

In a small bowl, whisk together 1 1/2 cups milk and cake flour. Mix into the Dutch oven.

Mix remaining milk, celery salt, salt, and pepper into the Dutch oven. Stirring occasionally, continue cooking the mixture about 10 minutes, until thickened.

Stir catfish into the mixture, and cook 5 minutes, or until fish is easily flaked with a fork. Mix in Cheddar cheese, and cook another 5 minutes, until melted.
