Mom's Clam Chowder

2 cans minced clams
2 c. peeled diced potatoes
1 c. onion, chopped
1 c. chopped celery
2 c. milk
1 tsp. salt
dash of pepper
1 c. evaporated milk
3/4 c. margarine
1/2 to 3/4 c. flour
2 cans cream of celery soup

Drain clams and set aside the juice. Put potatoes, onions and celery in a saucepan. Add clam juice and enough water to cover everything. Put the lid on and simmer vegetables over medium heat until tender. In another pan melt margarine. Slowly stir in flour, salt, and pepper. Gradually add milk and stir until it thickens. Add evaporated milk and soup. Stir. If mixture is too thick, add more milk until it is the desired consistency. Pour water off vegetables and add sauce. Put in the clams. Stir well and eat. I love this served in bread bowls! Such a great comfort food.
