Why is my purple sweet potato brown? So, I've seen a previous question about brown spots in purple sweet potatoes, but I have baked a potato that actually has a large brown... area. Is this spoilage? I ate a bite from the "top" area, where there is no brown blotch, and it tastes okay... but the "varied" color of the rest makes me nervous.
That's a yam, not a sweet potato. Looks like tropical rot. Probably had one or more insects get into it in the monsoon season. Looks like a fungus infection to me. Too wet a soil.
