What Are Cashews Anyway?
Cashews are the edible seeds of the cashew tree. These seeds are readily available in most grocery stores and offer a creamy, slightly sweet flavor. Besides being a popular snack, cashews serve as a key ingredient in vegan or vegetarian milk, creams, and cheeses.
Why Are Cashews Always Shell-less?
You might have noticed that you never find cashews with shells in stores. That’s because their shells contain a toxic oil that can cause skin irritation and even food poisoning. Rest assured, commercially available cashews are typically roasted or treated to neutralize any remaining shell oil, making them safe to consume.
Fun Facts About Cashews
Cashews have a unique growth pattern: they actually grow outside the apple-like fruit of the cashew tree, known as a cashew apple. Interestingly, cashew trees belong to the same plant family as poison ivy, which explains why you won’t find them in their shells. Did you know that the United States accounts for over 90% of global cashew consumption?

Do Cashews Go Bad?
Yes, cashews have a shelf life. Fresh cashews are aromatic, have a rich flavor, and provide a delightful crunch. But as they age, these appealing characteristics decline. However, proper storage can extend the life of your cashews significantly.
How Long Can You Keep Cashews?
Here’s a general guideline for cashew storage durations:
| **Storage Location | Raw Cashews | Opened Cashews | Unopened Cashews** |
| Pantry | 4 weeks | 2 weeks | Up to best-by date |
| Fridge | 6 months | 4 weeks | Up to best-by date plus 4 weeks |
| Freezer | 24 months | 6 months | Up to best-by date plus 12 months |
How to Tell If Your Cashews Have Gone Bad
- Visual Inspection: Discard any cashews that look deformed, have changed color, or show signs of mold.
- Smell Test: Fresh cashews have a pleasant aroma. If they smell sour or rancid, it’s time to toss them.
- Touch: Cashews should be firm and crisp. If they feel mushy or oily, do not eat them.
- Taste: Lastly, if the cashews taste off, they are likely past their prime.
Is It Safe to Eat Cashews Past Their “Best By” Date?
The “best by” date mainly indicates the peak quality period for the cashews, not their safety. If stored properly, cashews can be consumed even after this date, but be cautious about any signs of spoilage.
The Risks of Eating Spoiled Cashews
Eating a small amount of spoiled cashews is generally not dangerous but may cause stomach discomfort. Cashews contain a toxin called urushiol, which, in excessive amounts, can lead to hives or skin rashes.
Tips for Storing Cashews
- Pantry: Store them in an airtight container away from heat sources.
- Refrigerator: Ensure they are sealed tightly, as they can absorb moisture and odors.
- Freezer: Use freezer bags or airtight containers. Squeeze out excess air to maintain quality.
Can Cashews Be Frozen?
Absolutely, freezing cashews can extend their shelf life for up to a year, retaining their delightful crunch and flavor.
Conclusion
Cashews are not just a delicious addition to your diet; they are also a healthy one. Keep these nuts fresh by storing them correctly and being vigilant about their quality. With proper care, you can enjoy this nutritious snack without worry for a long time.
