Shrimp Creole

This recipe came from the chef of the M.S. Skyward, the Norwegian cruise ship of Mom's first Caribbean voyage.  It makes me wonder if she attended one of those on-board cooking demonstrations or just asked the chef for the recipe.  It is easy to see why this became one her favorite dishes.  It tastes wonderful and can be made in just minutes.

1 lb. raw shrimp, peeled and cleaned
1 cup green pepper, chopped
1 cup celery, chopped
1 cup onion, chopped
1 cup tomatoes, chopped
1 tablespoon shallots, sliced
1 bay leaf
salt & pepper
1 can tomato paste
juice of 1/2 lemon
2 cups water
2 tablespoons butter
1 tablespoon cornstarch
a few drops of tobasco

Melt butter in large pan.  Add onions, celery, shallots, and green pepper.  Saute for about 15 minutes.  Add shrimp, tomato paste and water.  Let simmer a few minutes.  Add tomatoes.  Dissolve cornstarch in a little water.  Stir into sauce.  Add lemon juice and season with salt, pepper and tobasco.  Serve over hot rice.
