What Exactly Is a Cashew?

The simple answer to "Are cashews nuts?" is a nuanced "no." While we treat them like nuts—eating them as snacks, adding them to recipes, and enjoying their nutty flavor—cashews aren't botanically classified as nuts. They belong to a different family entirely.

Cashews are technically drupes. This means they are the seeds of a fruit, encased in a shell. Many other fruits, such as peaches, plums and mangoes, also have drupes. Think of the hard shell surrounding the cashew as analogous to a peach pit. The edible part we consume is the seed within.

The Cashew's Unique Growth

Understanding why cashews aren't nuts requires looking at their growth. Cashews grow on a cashew tree, Anacardium occidentale, which produces a kidney-shaped seed (the cashew we eat) within a hard shell. This shell is attached to a fleshy fruit called the cashew apple. The cashew apple is edible and often used in juices and jams. The cashew nut itself grows at the end of a stem attached to the cashew apple. This unique growth pattern further distinguishes it from true nuts.

Botanical Classification: Nuts vs. Drupes

True nuts, like acorns, walnuts, and pecans, are dry fruits with a hard shell surrounding a single seed. They develop from a single ovary and are not fleshy fruits. The cashew, however, develops from an inferior ovary, resulting in the cashew seed being housed within a shell attached to a fleshy fruit, the cashew apple. This key difference in botanical development places cashews firmly in the drupe category, not the nut category.

Why the Confusion?

Despite not being botanically classified as nuts, cashews are widely accepted and used as a nut alternative. This is primarily due to their similar culinary applications, nutritional profile, and taste, which closely resembles other tree nuts. Their texture and flavor profile contribute to their widespread popularity and acceptance as a "nut."

Nutritional Benefits of Cashews

Regardless of their botanical classification, cashews offer a plethora of nutritional benefits:

Rich in healthy fats: Primarily monounsaturated fats, known for their heart-healthy properties.
Good source of protein: Contributing to a balanced diet.
Packed with minerals: Including magnesium, zinc, and iron.
Source of vitamins: Such as vitamin K and vitamin B6.
High in antioxidants: Helping protect cells from damage.

Cashews in the Kitchen: Culinary Applications

Cashews are incredibly versatile in the kitchen. Their creamy texture makes them perfect for:

Vegan cheese alternatives: Providing a rich and nutty flavor.
Cashew milk: A popular dairy-free milk alternative.
Smoothies: Adding creaminess and a boost of nutrition.
Stir-fries: For added flavor and texture.
Baking: A delicious ingredient in cookies, cakes and other desserts.

Conclusion: The Bottom Line

So, are cashews nuts? Botanically speaking, no. They are drupes – seeds of a fruit. However, their culinary uses, nutritional profile and common usage solidifies their place as a highly valued and delicious nut alternative. Their unique position between botanical classification and culinary use adds to their intriguing appeal.
