Clam Chowder

This is the one Alicia sent me. I need it somewhere where I can always find it so I'm posting it here.

Mom Morgan Boston Clam Chowda

2 cans chopped clams
1 cup onions, chopped fine
1 cup diced celery
2 cups diced potatoes
3/4 cup flour
1 cube butter
1 quart 1/2 and 1/2
1 1/2 tsp. Salt
Pepper
1/2 tsp sugar

Drain juice from clams and pour over veggies in medium saucepan. Add enough water to barely cover and summer until veggies are tender- about 20 min.

In the meantime melt butter; add flour and cook for a minute or two. Add cream and cook and stir until smooth and thick using a wire whisk to blend.

Add cooked veggies and clams and heat through. Season with salt, pepper and sugar. Optional: add thyme and marjoram to taste.
