Identifying Spoiled Walnuts

Rancid walnuts have a bitter taste and an unpleasant odor, similar to used cooking oil or rancid oil. Trust me, you'll know it when you smell it! If you ever come across walnuts that make you wrinkle your nose, it's best to leave them be. Nobody wants to eat bitter nuts, right?

Bad Walnuts: What They Look Like

Apart from the smell and taste, there are a few visual cues that can help you identify bad walnuts. Mold growth on walnuts is a clear sign of spoilage, so if you spot any fuzzy green or black patches, it's time to say goodbye to those nuts. Mold is a big no-no!

Another thing to look out for is the appearance of the shells. If the shells are dried out, shrunk, or look unhealthy, it's best to toss them out.

So, if you find a bag of walnuts in your pantry that's past its "expiration" date, don't panic! Give them a sniff and a taste test. If they still smell and taste fine, go ahead and enjoy them. However, if they smell off or taste bitter, it's best to let them go.

However, it's essential to use your judgment and trust your senses. If they don't smell or taste right, it's better to be safe than sorry and discard them.
