Using a 3 quart saucepan: Add salt pork and onions and cook over medium-low heat for 10-12 minutes. Add clam juice, 1 cup half & half, potatoes, and cook over medium heat for 10-12 minutes. Blend corn starch into 1 cup half & half, then add this, the cup of light cream, and clams to the saucepan. Bring heat to medium high, let mixture come close to a boil, stirring lightly; do not let mixture boil. Turn heat to low, add parsley, cracked pepper, and chopped chives, cook for 5 minutes. Remove and discard all of the salt pork. Stir gently and serve the chowder hot. Fresh homemade bread goes well with this chowder. Note: If you have access to fresh clams, use the equivalent amount of the fresh clams, saving the liquid the clams are packed in. You can use all light cream if you prefer, but that will greatly increase the calories per serving; the half and half works well for this recipe.
