Roasted Sweet Potato And Coconut Soup

INGREDIENTS

• • 4 MEDIUM SWEET POTATOES (ABOUT 1.5KG), HALVED LENGTHWAYS
  • 2 TABLESPOONS EXTRA VIRGIN OLIVE OIL
  • SEA SALT FLAKES
  • 400ML CAN COCONUT MILK, PLUS EXTRA TO SERVE
  • 3½ CUPS (875ML) CHICKEN STOCK
  • 1 STALK LEMONGRASS, HALVED AND BRUISED
  • 5CM-PIECE GINGER, HALVED
  • 3 KAFFIR LIME LEAVES
  • DRIED CHILLI FLAKES, TO SERVE

METHOD

1. Preheat oven to 220°C (425°F). Place the sweet potato, cut-side up, on a large oven tray lined with non-stick baking paper. Drizzle with the oil and sprinkle with salt. Cover with aluminium foil and cook for 1 hour or until tender. Set aside until cool enough to handle.
2. While the sweet potato is cooking, place the coconut 
milk, stock, lemongrass, ginger and lime leaves in a large saucepan over high heat and bring to the boil. Remove from the heat. Remove and discard the lemongrass, ginger and 
lime leaves.
3. Using a spoon, scoop out the flesh of each sweet potato, discarding the skins, and place in a blender. Add half the coconut mixture and blend until smooth. Return to the saucepan with the remaining coconut mixture and cook over low heat, stirring constantly, until smooth and hot.
4. Divide the soup between bowls. Top with the extra coconut milk and sprinkle with chilli flakes to serve.
