Preparation To render fat, cook chopped bacon in heavy large saucepan over medium-high heat 5 minutes. Add chopped onions and sauté until onions are translucent, about 8 minutes. Add curry powder and stir 30 seconds. Mix in bottled clam juice, diced potatoes, diced butternut squash and bay leaves. Simmer 5 minutes. Add chopped kale leaves and simmer until vegetables are almost tender, about 10 minutes. Add 5 cups milk, 1 cup half and half and minced thyme. (Chowder can be prepared 1 day ahead. Cover tightly and refrigerate.) Bring chowder to simmer. Add fish and simmer until cooked through, about 3 minutes. Season to taste with salt and pepper. Discard bay leaves. Ladle chowder into bowls and serve.
