1 brown onion
4 cloves garlic, crushed
2inch piece of fresh ginger, sliced
3 cups mashed roasted sweet potato
3 Tbsp miso
4 cups vegetable or chicken stock
Yoghurt drizzle: 1/2 cup yoghurt, 1/2 tsp garam masala, 1/2 Tbsp maple syrup
Cook the onion and garlic in the olive oil over medium heat until soft and translucent. Raise the heat a little and add the ginger. Fry until the ginger is fragrant, but don't let the onions and garlic brown. Add the sweet potato mash and miso, and continue cooking until the puree is warmed.
Add the stock to the pan and stir to combine. Bring to a simmer, then cover, turn the heat to low, and let the soup cook for about 5 minutes to bring the flavours together. Remove from heat and puree.
Whisk together the yogurt, garam masala, and maple syrup. Drizzle over the sweet potato soup to garnish.
