1. Prepare the Vegetables: Peel and cut the cassava, sweet potato, yam, eddoes, and plantain into medium-sized pieces.
2. Make the Dumplings: Mix flour and salt in a bowl. Gradually add water and knead into a firm dough. Divide into small pieces and shape into short dumplings.
3. Start the Coconut Broth: In a large pot, combine coconut milk, water or vegetable broth, onion, garlic, spring onion, thyme, black pepper, and hot pepper.
4. Add the Root Vegetables: Add the cassava, yam, and eddoes to the pot. Bring to a gentle boil, then reduce the heat and simmer for about 15 minutes.
5. Add the Remaining Vegetables: Add sweet potato and plantain. Continue cooking until the vegetables begin to soften.
6. Add the Dumplings: Place the dumplings into the simmering broth and cook for another 10–15 minutes, stirring gently to prevent sticking.
7. Check for Doneness: Cook until all root vegetables are completely tender and the dumplings are cooked through. Cassava should be thoroughly cooked before serving.
8. Adjust and Serve: Taste and adjust the salt and seasoning. Let the stew simmer briefly until the coconut broth reaches a creamy consistency. Serve hot.
