So, what are the telltale signs that your rhubarb has gone bad? Well, first things first, take a whiff - if it smells sour or fermented, it's likely past its prime. And, let's be real, if it's slimy or mushy, it's time to say goodbye.
Next up, take a gander at the color - if it's turned from a lovely green to a brownish-red, it's on its way out. And, don't even get me started on moldy leaves - that's just a no-go. But, don't worry, these signs are easy to spot, and with a little practice, you'll be a rhubarb expert in no time.

Now, I know what you're thinking - what about the stems? Well, my friend, the stems are a great indicator of freshness. If they're limp or wilted, it's likely that your rhubarb has seen better days. But, if they're still crunchy and firm, you're good to go.
