Cashews are tropical nuts with a moderate oil content and low moisture, making them fairly shelf-stable when stored properly. They are sensitive to heat and humidity, which can cause rancidity.
To extend their shelf life, cashews should be stored in cool, dry conditions and kept in airtight containers. Refrigeration is recommended for long-term storage, especially for raw or roasted cashews. Proper handling preserves their creamy texture, rich flavor, and nutritional value.
