Raw kaju on a pack is not the same as raw in the shell
You may have seen the warning that raw cashews are poisonous. Then you see a pack of “raw kaju” in the shop and wonder what to believe. The raw vs roasted cashews question has a plain answer, and it is calmer than the scare.
The cashews you buy in a pack have been through heat before they reach the shelf. “Raw” tells you the kernel was not roasted or salted for flavour. Whole nuts still in the shell are not sold to home buyers.
This guide explains what the label means, how raw and roasted compare on taste, sodium and shelf life, and which one to buy for each job. We do not sell cashews at the moment, so the products page shows what we do sell.
Are raw cashews from a shop safe to eat?
Yes. Raw cashews sold in packs are safe for most people. The kernels are heat-processed before sale, which removes the irritant oil found in the shell. Truly unprocessed cashews in the shell are not sold to shoppers. Anyone with a tree nut allergy should avoid all cashews.
The cashew shell holds an oil with compounds related to those in poison ivy. That is where the “poisonous” story comes from. The oil can cause an itchy skin rash. Healthline explains that shelled cashews are steamed or briefly heated before sale, and that this removes the irritant.
There is a real case on record. In April 1982, a rash hit 54 of 274 people who ate cashew pieces at a Pennsylvania event. The US CDC report links it to cashew shell oil on incompletely processed nuts, and 5 of 14 bags opened held shell fragments. It was a processing failure, not a flaw in normal packs.
In practice, buy from a seller who sells clean, whole kernels in a sealed pack. Do not eat any pack that contains bits of brown shell. Cashew allergy is a separate issue: heat does not remove it. If anyone in your family has a nut allergy, or you are buying for a child, check with your doctor first.
What does “raw” mean on a kaju pack?
“Raw” on a kaju pack means the kernel has not been roasted, salted or flavoured after shelling. It does not mean uncooked or unprocessed. The nut was still heated once to deal with the shell oil, then dried and peeled.
So raw kaju is “raw” only in the shopper’s sense. It is pale, creamy white, slightly soft and mildly sweet. It has the cleanest taste, which is why cooks prefer it.
Roasted cashews go through a second round of heat. They turn golden, crisper and nuttier. Salt, oil or spices are often added after that.
The gap in kernels also matters. Raw kaju is sold by size grade, such as W180 or W320, and roasting does not change the grade. Our guide to cashew grades explains the numbers. Pale, even colour is a sign of good raw kaju, covered in how to identify good quality cashew nuts.
How do raw and roasted cashews compare on taste and texture?
Raw cashews taste mild, creamy and faintly sweet, with a soft bite. Roasted cashews taste toasted and nutty, with a sharper crunch. Salted roasted kaju is the snack, and raw kaju is the ingredient.
Say you are making kaju katli for Diwali. Roasted nuts would taste toasted in the barfi, and the colour would turn dull instead of white. Raw is the right pick.
Say you are making a rich shahi paneer gravy. You soak raw kaju and grind it to a smooth paste. Roasted salted nuts would add salt you did not plan for and would not blend as creamy.
Now say you want something to eat with evening chai. Raw kaju tastes a little flat on its own. A roasted, lightly salted kernel is far more satisfying.
You do not have to buy two packs. You can roast raw kaju yourself in a dry pan on low heat for a few minutes, until it turns light gold. That gives you roasted flavour with no salt, and you decide how far to go.
How do raw and roasted cashews compare on nutrition and salt?
Raw and roasted cashews have similar protein and fat. The big difference is salt. USDA data lists about 4.8 mg of sodium in 100 g of raw cashews and 640 mg in dry roasted, salted ones. Roasting alone adds none.
These are USDA values per 100 g of kernels, as shown on a data site that reproduces USDA FoodData Central. They are two separate USDA entries, not one nut measured before and after.
| Per 100 g of kernels | Raw | Dry roasted, salt added |
|---|---|---|
| Energy | 533 kcal | 574 kcal |
| Protein | 17.4 g | 15.3 g |
| Fat | 38.9 g | 46.4 g |
| Sodium | 4.8 mg | 640 mg |
Sources: raw cashew nuts and dry roasted cashew nuts with salt added.
Do not read the small energy and protein gaps as a reason to choose one. They reflect different samples and the salt and oil in the roasted entry. Sodium is the number that matters.
How much sodium is in a handful of salted cashews?
A 30 g handful of dry roasted, salted cashews has about 190 mg of sodium, using the USDA figure of 640 mg per 100 g. That is roughly 10% of the 2,000 mg daily limit WHO recommends for adults.
The sum: 640 mg x 0.3 = 192 mg. WHO recommends less than 2,000 mg of sodium a day, which is under 5 g of salt.
One handful is fine for most people. A bowl that keeps getting refilled is not, especially on top of namkeen, pickle and papad. If you have high blood pressure or kidney disease, or your doctor has limited your salt, ask which type suits you. Raw is the simpler choice.
Does roasting change shelf life and freshness?
Yes, a little. Roasted and salted cashews usually go stale sooner than raw ones, because heat and added oil speed up rancidity. Any cashew kept in a warm, humid kitchen turns soft or rancid faster than one kept cool and sealed.
We could not find a tested shelf life that compares raw and roasted kaju directly, so take that point as a general rule. What is clear is the range for opened cashews. StillTasty gives about 1 month in a cool pantry, 4 to 6 months in the fridge and 9 to 12 months in the freezer, for best quality.
Indian summers and monsoon make the pantry figure optimistic. Our guide on how to store cashews in India covers jars, fridge use and the moisture problem.
So buy raw in a bigger pack if you cook often. Buy roasted in a size you will finish in a few weeks.
Which should you buy: raw or roasted cashews?
Buy raw kaju for curries, cashew paste, kaju katli and other sweets. Buy roasted for snacking, travel and a party bowl. If you watch salt, choose raw or roast it yourself. Neither is the healthier nut in every case.
Match the pack to the job:
- Curry gravies and cashew paste: raw. It blends smooth and keeps the gravy mild.
- Kaju katli, barfi and kheer: raw. The colour stays pale and you control the sweetness.
- Evening snack or a party bowl: roasted salted. It is ready to eat.
- Daily snacking with limited salt: raw, or home-roasted without salt, in a measured portion.
- Cooking for guests with allergies or a child: raw or roasted makes no difference. Cashew is a tree nut, so check with a doctor.
- Gifting: roasted looks and tastes festive. Raw suits a cook.
The honest answer is that roasted is the better snack and raw is the better ingredient. If you are not sure, buy raw. You can always roast it, and you cannot un-salt a salted pack.

How can you check roasted cashews are fresh?
Smell and taste one. Fresh roasted cashews smell sweet and toasty and snap when bitten. A sharp, bitter or paint-like smell means rancid oil. A soft, chewy or damp kernel means it has absorbed moisture and is past its best.
Use these checks before you buy or eat:
- Look at the colour. Light gold and even is good. Dark brown patches suggest over-roasting or age.
- Smell the pack. It should smell nutty and clean. Any oil-paint smell means skip it.
- Check the crunch. A fresh kernel snaps. A bendy one is stale.
- Read the label. Look for cashews and salt, with a date you can read. Extra flavourings and oils mean a more processed snack.
- Taste one nut. It should taste of kaju first and salt second.
If a pack fails the smell test, do not eat it. Cooking will not fix a rancid nut.
Frequently asked questions about raw and roasted cashews
Are raw cashews poisonous?
No, not the ones sold in packs. The poison story comes from the irritant oil in the cashew shell. Shop-bought kernels are heat-processed to remove it. Nuts in the shell are not sold to shoppers.
The CDC’s 1982 report involved incompletely processed pieces with shell fragments. Check your pack for brown shell bits and buy from a seller you trust.
Is raw kaju healthier than roasted?
Not by much. Protein and fat are similar. The main difference is sodium: about 4.8 mg per 100 g in raw and 640 mg in dry roasted, salted cashews, per USDA data. If you must limit salt, raw is simpler.
If you roast raw kaju yourself without salt, you get the flavour and none of the sodium.
Can I use roasted cashews for kaju katli?
You can, but raw gives a better result. Roasted nuts add a toasted flavour and a darker colour, and salted ones add salt to the sweet. Use raw kaju for katli, barfi and cashew paste.
If you only have roasted unsalted kaju, grind it fine and skip any extra salt in the recipe.
Should I soak raw cashews before use?
Soak raw cashews in warm water for 15 to 20 minutes before grinding them for gravies and creamy sauces. It softens them for a smooth paste. You do not need to soak kaju you will eat as a snack.
Drain the water before blending. For sweets, grind the nuts dry.
Can children and pregnant women eat raw cashews?
Packaged raw cashews are generally fine as food, but whole nuts are a choking risk for very young children. Cashew is a tree nut and a common allergen. Check with your doctor or paediatrician for pregnancy, children and allergies.
Chopped or ground kaju is safer for small children.
Buy raw for the kitchen and roasted for the bowl
Raw kaju is the safe, flexible choice. It makes the creamiest gravies and the whitest sweets, and you control the salt. Roasted salted kaju is the better snack, as long as you watch the bowl.
Read the label, smell the pack and buy a size you will finish while it is fresh. We do not sell cashews right now, but you can see our range on the products page, including our Kashmiri Mamra Badam.
