Interesting facts  that even many people in the industry misunderstand.

Many people assume cashews are similar to almonds, chestnuts, or walnuts that they belong to the group of “nuts” that grow inside a fruit or within a hard shell.

But the truth is:

Cashews are actually classified as seeds. They grow outside the cashew fruit, attached beneath the cashew apple. This is one of nature’s most fascinating structures that often goes unnoticed. If you look closely, you will notice:

• Mango seeds grow inside the fruit
• Jackfruit seeds grow inside the fruit pods
• Durian seeds grown inside the flesh
• Cashew seeds grow outside the fruit

This is why many people are surprised the first time they see a real cashew fruit.

Cashew apple is a false fruit (accessory fruit). The true fruit is the kidney-shaped structure hanging underneath which contains the cashew seed we eat.

Are there other seeds that grow outside the fruit like cashews?

Yes, but they are quite rare, and their biological structures are different. A fascinating example is the strawberry. The tiny “seeds” on the outside of a strawberry are actually the true fruits, while the red fleshy part we eat is enlarged flower tissue. However, strawberries and cashews develop in very different ways.

Most fruit bearing plants keep their seeds inside the fruit. Cashews are unusual because the seed develops outside the cashew apple, giving the tree a very distinctive appearance. The yellow or red structure that most people call the “cashew fruit” is not the true fruit in botanical terms. It is actually an enlarged flower stalk. This unique arrangement makes the cashew tree one of the most remarkable fruit-bearing crops in agriculture.

Cashew nuts naturally contain a compound that can cause irritation

This is something that even many people in the industry do not fully understand.

Inside the hard shell of a raw cashew nut is a natural compound called anacardic acid. This substance is mildly caustic and can cause skin irritation, burning sensations, or discomfort when handled in large amounts.

This is why:

• Workers who manually shell cashews often wear protective equipment
• Fresh, unprocessed cashews cannot be eaten directly
• Proper heat treatment is an essential step in cashew processing.

If the processing is not done correctly, oils and residues from the shell can affect both the flavor and the eating experience.

Are roasted cashews still toxic?

When cashews are processed using proper techniques, most irritating compounds are removed during steaming, drying, and high-temperature roasting.

That is why properly processed cashews are completely safe to enjoy as a nutritious food. Cashews are naturally rich in:

• Healthy fats
• Plant-based protein
• Magnesium, zinc, and iron
• Various beneficial minerals

However, the final quality of the product still depends greatly on how the cashews are handled before, during, and after processing.

What many customers like about Dong Phu Cashew

A great cashew is not simply one that is large and attractive. It should also have:

• A naturally rich aroma
• Deep buttery flavor
• A clean finish
• No harshness in the throat
• No unpleasant aftertaste

That is why we continuously refine our processing methods to minimize any harsh oils or residues that may remain from the shell.

Many customers have shared that:

Dong Phu Cashews can be enjoyed even with the thin skin intact, without causing throat irritation or the harsh sensation sometimes found in other products on the market.

This is something we take seriously because it directly affects the customer experience.

For us, producing quality cashews is not simply about roasting them until they’re cooked. It means understanding the nature of the seed, mastering the right processing techniques, and caring about how customers feel after every bite.

That commitment is how Dong Phu Cashew has maintained its unique identity throughout many years in the industry.
