Step 1: In Dutch oven or large saucepan melt 3/4 cup butter over medium-high heat. Add in onions, carrots and celery, cayenne and black pepper; saute until softened and very tender, about 6 minutes (adding in the garlic the last 2-3 minutes of cooking, all veggies must be tender it may take more that 6 minutes).
Step 2: Mix in both cans condensed potato soup and two cans of clams with their juice.
Step 3: Drain and discard the juice from the remaining can of clams, then add the clams to the soup.
Step 4: In a small bowl or cup whisk the cornstarch with 1/2 cup cold cream until smooth; add to the soup stirring constantly, then add in the remaining 3-1/2 cups light cream; bring to a boil stirring until thickened and heated through. Season with salt and more black pepper to taste. Ladle into bowls and sprinkle Parmesan cheese on top.
