Place the agar agar chunks in in a large saucepan with 2 cups of water and let soak for 20 minutes. Place the squash chunks and sea salt in the saucepan, cover and ring to a boil. Reduce the flame to low and simmer until the squash chunks are tender, about 7 to 10 minutes. Pour squash and all cooking water into a blender and puree until smooth. Pour into a shallow bowl or mold. Refrigerate to gel. While the aspic is gelling, prepare the dressing by placing all ingredients, except the parsley, into a blender and puree until creamy. When the aspic is firm, slice, and serve with dressing and garnish with parsley.
