Steam the potatoes until they are 70% done. Preheat the oven to 180 °C-200 °C. Mix the coconut milk with the herbs and salt. Add this to the wedges and toss to coat them thoroughly. Spread wedges on a baking tray lined with parchment paper and bake for 15-20 minutes. Then, turn the wedges over and bake for another 5-10 minutes.
Enjoy with home-made ketchup or green chutney.
