Here’s the big rule: if your sweet potato feels mushy when you squeeze it, like a stress ball that’s been left in the sun, toss it. Same goes if you see any oozy, wet patches. That’s rot, my friend—not a new flavor profile.
And if it smells sour or like a damp basement? Trust your nose. Your nose is a genius at detecting bad sweet potatoes. Don’t argue with your nose.
