Put the remaining 4 cups vegetable stock, the potatoes and the onion into a large pot. Bring to a simmer, cover and cook for 5 minutes. Stir in the broccoli and basil and return to a simmer. Cover and cook until the potatoes are tender, about 10 minutes. Stir in the reserved cashew mixture, the salt, the pepper and bring just to a simmer.
