Take the dried winged kelp and place in a bowl of water for 5 minutes to rehydrate. Drain the butare from the water and cut with a sharp knife so the are no pieces larger than 1 cm. Add the Winged kelp to the pot and stir through.
Add curry, cumin and turmeric to the pot and mix through. Cook for 5 more minutes or until aromatic.
Add the lentils, coconut milk and broth and bring heat down to low-medium. Place a lid on the pot and stir periodically every 5-10 minutes.
After 30 minutes or so the lentils should have softened and soaked up a lot of liquid. Once the lentils feel soft to chew, season the dahl with salt and pepper.
