After a few weeks, check them with a little TLC. Look for soft spots, oozing, or a funky smell. A small bruise is fine—just cut it off like you’re performing potato surgery. But if it’s mushy or smells like last week’s gym sock, toss it immediately.
Here’s a fun rule: if a sweet potato is wrinkled and bendy, it’s past its prime but might still be okay for mashing. If it’s leaking and smells like a swamp, it’s ghost potato—deceased, departed, done for. Say a quick eulogy and move on.
