Cashews: Are They Nuts or Seeds? Unraveling the Mystery

Cashews, with their rich, buttery texture and versatile uses in both savory and sweet dishes, often raise the question: are they nuts or seeds? This article delves into the botanical classification and culinary uses of cashews, revealing the fascinating truth behind these beloved nuts.

Botanical Classification: Nuts or Seeds?

Cashews, botanically speaking, are not true nuts. They belong to the family Anacardiaceae, alongside species such as mangoes, sumacs, and pistachios. Cashews are actually seeds, specifically of a drupaceous fruit. A drupaceous fruit, or drupe, is a fruit that contains a single hard seed or pit surrounded by a starchy or fleshy fruit. In the case of cashews, the seed (which we consume as a “nut”) grows outside the fruit, making it distinct from true nuts like walnuts and almonds.

The Cashew Tree and Its Fruit

The cashew tree (Anacardium occidentale) produces a fruit known as the cashew apple, which is edible and often used in juices, jams, and other culinary preparations. The cashew nut, which is the seed of this fruit, grows at the base of the cashew apple. It is in this unique position outside the fruit that sets cashews apart from other nuts and seeds.

Culinary Uses and Nutritional Benefits

In culinary contexts, cashews are commonly referred to as nuts due to their characteristic taste and texture. They are a popular snack and can be found in a wide range of dishes, from stir-fries to desserts. Cashews are also a nutrient-dense food, rich in minerals, proteins, and healthy fats. A 100-gram serving of raw cashews contains approximately:

This makes cashews a valuable addition to a balanced diet, especially for those looking to boost their intake of essential nutrients.

Safety and Harvesting

Cashews, both the apple and the nut, require careful handling due to the presence of urushiol, a chemical compound similar to that found in poison ivy. To safely harvest and process cashews, the outer shell must be removed, often by hand or machine. This process can be complex and potentially harmful, as the chemical can cause dermatitis if not handled properly. Unfortunately, this process can often be hazardous for workers in developing countries, particularly if they do not have access to protective gear like gloves.

Global Production and Market Dynamics

Today, the world's largest producers of cashew nuts are India and Vietnam, followed closely by Nigeria and other African countries. The production and processing of cashews are significant factors in the economies of many of these regions. The cashew apple, while not as widely consumed in the West, is favored in other parts of the world for beverages and other food preparations. In Goa, for example, a traditional alcoholic beverage made from cashew apple pulp, called feni, is a beloved local delicacy.

Conclusion

In summary, cashews are technically seeds, distinct from true nuts. Understanding this botanical truth can enhance our appreciation for their unique nutritional profile and versatile culinary applications. Whether you're enjoying a handful of cashews as a snack or incorporating them into your favorite dishes, the knowledge that you're consuming a seed with a rich history and diverse uses is a fascinating fact to keep in mind.
