Rinse madhumbe and put in a saucepan and add water. Bring to a boil for about 10 minutes. Drain the water and peel the skin off madhumbe. Cut into wedges.

Preheat oven to 450 degrees. Lightly grease two large baking sheets.

Whisk together oil and spices. In a large bowl, toss madhumbe wedges in oil and seasoning mixture to coat well.

Arrange madhumbe on prepared pans in a single layer. Roast madhumbe  for 20-25 minutes (or until tender), flipping them and rotating pans halfway through baking. Season with additional salt, if needed.

Serve madhumbe with tomato sauce (ketchup).
