The Dual Identity of Cashew - Fruit and Nut Explained

1. Cashew is a fruit or seed
Cashew is actually both! The cashew tree produces two distinct parts: the cashew apple and the cashew nut.

Cashew Apple: This is the fleshy, pear-shaped structure that grows on the tree. It's technically the swollen stem and is edible. People often use it to make juices, jams, or even alcoholic beverages.
Cashew Nut: This is the true seed of the cashew tree, found at the bottom of the cashew apple. It's encased in a hard shell that contains toxic oil, which is why cashew nuts are always sold shelled.

So, when you enjoy cashews, you're actually eating the seed of the cashew fruit.
2. Full explanation about cashew fruit
The cashew fruit is quite unique and fascinating. Here's everything you need to know about it:
Structure of the Cashew Fruit

Cashew Apple: This is the swollen stem of the cashew tree. It has a juicy, fibrous, and pear-shaped body, usually yellow or red. Despite its name, the cashew apple is not a true fruit but is often referred to as one due to its appearance and juicy nature. It is edible and can be consumed fresh, juiced, or used to make alcoholic beverages like feni in Goa, India.
Cashew Nut: This is the true fruit of the cashew tree, located at the bottom of the cashew apple. The nut is encased in a hard shell that contains a toxic oil called urushiol, which can cause skin irritation. This is why cashews are never sold in their shells.

Uses of the Cashew Fruit
Cashew Apple:

Culinary Uses: The cashew apple is eaten fresh in some cultures, but its high tannin content can make it a bit astringent. It is more commonly used to make juices, jams, chutneys, and alcoholic beverages.
Health Benefits: It is rich in vitamin C, calcium, and other nutrients, making it a nutritious snack.
Cashew Nut:
Culinary Uses: The nut is the most valued part of the cashew fruit. After removing the toxic shell through roasting or steaming, the nuts are consumed raw, roasted, or used in various recipes. Cashew nuts are popular in confectioneries, cooking, and as a standalone snack.
Health Benefits: Cashews are packed with nutrients, including healthy fats, proteins, vitamins, and minerals. They are beneficial for heart health, bone strength, and weight management.

Processing the Cashew Nut
The processing of cashew nuts is labor-intensive due to the toxic shell. Here are the steps:

Harvesting: The cashew apples are collected from the trees.

Separation: The nut is separated from the apple.
Roasting/Steaming: The nuts are roasted or steamed to soften the shells and neutralize the urushiol.
Shelling: The shells are then removed, either manually or with machinery, to extract the kernel.
Peeling: The thin, inner skin of the nut is peeled away.

Drying: The kernels are dried to reduce moisture content and enhance shelf life.
Grading: The cashews are graded based on size and quality before packaging.

Economic Importance

Cashew trees are primarily grown in tropical regions, with significant production in countries like India, Vietnam, Nigeria, and Brazil. The cashew industry supports the livelihoods of millions of farmers and workers in these regions. Cashew products, including nuts and derivatives like cashew butter, cashew milk, and cashew oil, have high economic value.

Fun Facts
