Add the soaked cashews to a blender with 1 cup of water. Blend until you have a super smooth "cashew cream", and set aside.
In a large pot over medium heat, melt the butter or ghee. Add the onion and celery and sauté until softened, about 5 minutes. Stir in the arrowroot.
Add the potatoes, water, broth, and juice from the clams. Stir in the bay leaves and dried herbs, and bring the soup to a low boil. Reduce the heat to low and simmer for 15-20 minutes, or until the potatoes are tender.
Remove the bay leaves from the soup. Add the cashew cream, clams, and shrimp, and stir until combined. Return to a simmer and cook for 5 minutes or until the shrimp is cooked through (it will be firm & opaque).
Season with salt & pepper to taste, and top with bacon & chives. Enjoy!!
