Walk into any dry fruit shop in India and you will usually find two kinds of walnut: Kashmiri, and imported, which mostly means Californian or Chilean. They look different, taste different and are priced differently. Neither is a scam. They are simply different products, and which one is right depends on what you are doing with it.

Where each comes from

Kashmir grows the large majority of India's walnuts. The trees are mostly old seedling trees scattered through villages and hillsides rather than planted in uniform irrigated orchards, which is why the nuts themselves are so variable. Imported walnuts typically come from large commercial orchards growing a single variety such as Chandler, bred for size, pale colour and consistency.

Side by side

Kashmiri walnuts are not one thing

In the local trade, in-shell walnuts are sorted by shell type:

• Kaghzi (paper shell): thin shell you can often crack by hand, large kernel. The premium in-shell grade.
• Burzil: medium shell. Needs a cracker. The everyday walnut.
• Wonth: very hard shell, small kernel that is difficult to extract whole. Traditionally used more for oil.

If a listing just says Kashmiri walnuts in shell, it is worth asking which of these you are getting, because the amount of edible kernel per kilo differs a lot.

What buyers should actually look for

If you are buying kernels

• Halves or pieces? Halves cost more because they are harder to extract whole. For baking, chutney or halwa, pieces are the smarter buy.
• Colour grade. Light kernels are milder and look better. Amber kernels are slightly stronger. Both are fine if fresh. Very dark, shrivelled kernels are not.
• Crop. New crop arrives from October. Ask.
• Smell on arrival. Walnut oil turns rancid faster than almost any other nut. A sharp, paint-like smell means the bag is past it, however good it looks.

If you are buying in shell

• Expect roughly 40 to 45 percent kernel by weight. A kilo in shell gives you 400 to 450 grams of food. Compare prices on that basis.
• The nut should feel heavy for its size and should not rattle. A rattle means the kernel has dried and shrunk.
• Avoid shells with cracks, holes or dark damp stains.
• Very white, bleached-looking shells have been cosmetically treated. Natural shells are light brown and uneven.

Kernels or in shell?

The shell is the best packaging a walnut will ever have. In-shell walnuts stay fresh far longer, which makes them the better choice if you eat walnuts slowly or want to store them through the year. Kernels are for convenience and for cooking. If you buy kernels, buy smaller quantities more often and keep them in the fridge. Details in how to store Kashmiri dry fruits.

So which should you buy?

• For eating as they are, for flavour: fresh-crop Kashmiri. The taste is the reason people ask for them by name.
• For a gift tray or cake decoration where looks come first: imported halves are more uniform, and there is no shame in that. Kashmiri light halves also work if the seller grades properly.
• For baking and cooking: Kashmiri pieces. You get the flavour and do not pay for appearance.
• For long storage: Kashmiri in shell.

One thing to be wary of

Because Kashmiri walnuts carry a name, imported or mixed-origin kernels are sometimes sold under it. Perfectly uniform, very large, very pale kernels at a Kashmiri label are worth a question. Real Kashmiri stock looks like it came from many different trees, because it did. The general checks for any seller are in our guide on how to buy Kashmiri dry fruits online.

Common questions

Why are some of my Kashmiri walnuts bitter?

Usually age rather than variety. Most bitterness sits in the skin and gets stronger as the oil oxidises. Fresh crop, stored cold, is noticeably sweeter.

Are lighter kernels better quality?

They are a higher appearance grade and milder in taste. Freshness matters more than shade.

Can I tell Kashmiri from Californian by looking?

Often, yes. Californian kernels are larger, paler and strikingly uniform. Kashmiri kernels are smaller and mixed in shade.
