Oyster stew

Hi does anyone have a recipe for oyster stew?  I do not have a double boiler and I was wondering if it is necessary to make this stew.  Looking forward to hearing from you.

Yes, don't even attempt it without a double boiler - or buy a $$$$  steamer like they use at the Grand Central Oyster Bar.

Cheers, John 

A double boiler makes things a lot easier, but if you don't want to invest in one, here are a couple of recipes not using a double boiler:

(Just make sure you don't leave the kitchen or get interrupted while making it.)

A double boiler isn't necessary if you keep the heat low enough so that it doesn't go above a simmer but most people are too impatient for that.

Here's one of my favorite oyster stew recipes for when I want a change from the basic.

OYSTERS ROCKEFELLER STEW – 4 servings
.
4 slices bacon
1 cup thinly sliced leeks
1 cup thinly sliced celery
1/ 8 tsp. cayenne pepper
3 cups half-and-half
2 cups milk
1 1/ 2 pints shucked oysters and liquor
2 tsp. Worcestershire sauce
2 cups thinly sliced raw spinach leaves
Salt and black pepper
1 Tbs. butter (optional)
Oyster crackers to serve with stew
.
In a large heavy saucepan or soup kettle, fry the bacon until crisp. Drain on paper towel, crumble and reserve. Pour off all but 2 Tbs. of drippings from the skillet.
.
Add the leek and celery and saute over medium-low heat for 8-10 minutes, until the vegetables are softened. Stir in the cayenne pepper.
.
Add the half-and-half and the milk and bring to a simmer. Add the oysters (cut large ones in half) and the Worcestershire sauce. Return to a simmer. Stir in the spinach and simmer for about 5 minutes, until the spinach is just wilted and the oysters are cooked through. Add salt and pepper to taste.
.
Swirl in the optional butter, if used, and serve immediately in large, shallow bowls. Sprinkle each bowl with the reserved bacon.
