Method
1. In a large pot, melt the butter. Add the onion and garlic. Saute for 4 or 5 minutes until softened, but not browned. Add the kumara and stock. Cover and cook for 20 minutes until the kumara is completely soft. Add the puha or watercress and continue to cook for 5 minutes.
2. Using a stick blender or kitchen blender puree until very smooth. Return to a clean pot.
3. For the garish, heat an oven to 180degC. Place the sliced kumara in a single layer on to a lined baking dish. Rub kumara completely with oil and sprinkle with salt. Roast for 20 minutes until golden and crispy.
4. Reheat the soup, add the cream, season with salt and pepper. Serve hot with crispy kumara chips on top and a little puha or watercress. — Viva.co.nz
