Characteristics
- Cashew Apple: The cashew apple is a fleshy, pear-shaped structure that is yellow, orange, or red in color. It is juicy and slightly sweet but is not commonly exported due to its perishable nature.
- Cashew Nut: The cashew nut is actually a seed that grows at the bottom of the cashew apple. It is encased in a hard shell that contains a toxic substance called urushiol.
Culinary Uses
Cashews are versatile in culinary applications:
- Snacks: Eaten raw, roasted, salted, or flavored.
- Cooking and Baking: Used in stir-fries, curries, salads, desserts, and granola.
- Dairy Alternatives: Processed into cashew milk and cashew-based cheese.
- Nut Butters: Ground into cashew butter, a popular spread.
- Flour: Used as a gluten-free flour alternative in baking.
Nutritional Profile

- Macronutrients: High in healthy fats (primarily monounsaturated and polyunsaturated fats), moderate protein, and low in carbohydrates.
- Vitamins and Minerals: Rich in copper, magnesium, manganese, phosphorus, vitamin K, and zinc.
- Antioxidants: Contain antioxidants such as polyphenols and carotenoids.

- Blood Health: Iron and copper in cashews contribute to healthy red blood cell production and prevent anemia.
- Skin and Hair Health: Nutrients like zinc, antioxidants, and healthy fats promote healthy skin and hair.
Processing
The processing of cashews is intricate due to the presence of urushiol in the shell:
- Harvesting: Cashews are harvested from the tree when the cashew apples fall to the ground.
- Shelling: The nuts are separated from the apple and then steamed or roasted to make shell removal easier and to deactivate the urushiol.
- Drying: The shelled nuts are dried to reduce moisture content and improve shelf life.
- Peeling: The thin skin covering the nut is removed to produce the final product.
Safety and Precautions
- Allergies: Cashews can cause allergic reactions in some individuals, similar to other tree nuts.
- Raw Cashews: Cashews sold as "raw" are typically steamed to remove toxins. Truly raw cashews, with their toxic shells, are not safe to eat.
Storage
- Shelf Life: Cashews have a long shelf life if stored properly.
- Conditions: Store in an airtight container in a cool, dry place. Refrigeration or freezing can extend their freshness and prevent rancidity.
- Avoid Moisture: Keep away from moisture to prevent mold growth.
