Cashews

What it is

The kidney-shaped nut that grows attached to the cashew apple. Always sold shelled and processed — never raw in-shell, because the shell contains caustic, irritant oils (related to poison ivy).

How it's made

The nut is carefully roasted/steamed to neutralize the toxic shell oil (urushiol-like), then shelled — a hazardous, labor-intensive process. Sold raw (technically already processed) or roasted. Ground into a smooth paste, cashews make an extraordinarily creamy, neutral base.

Flavor profile

Mild, sweet, buttery, creamy, with a soft, almost fatty texture and very little bitterness — the most neutral and creamy of the common nuts, which is exactly why it's such a useful thickener.

Culinary uses

A crucial sauce-thickener in South Asian cooking: ground cashews (kaju) give Mughlai korma, butter chicken gravy, and rich North Indian curries their silky, creamy body without dairy. In West African cooking, cashews and cashew apples are used, and the tree is a major crop. In Southeast Asia (Thai, Vietnamese), whole roasted cashews go into stir-fries (cashew chicken) and salads. Ground raw cashews are the backbone of vegan cream sauces, "cheeses," and desserts thanks to their neutral creaminess. Toasted whole as a garnish and snack.

Regional variations

India: kaju paste in curries and kaju katli (cashew fudge sweet). Thailand/Vietnam: cashew stir-fries. West Africa (and Brazil, the cashew's origin): the tree and cashew apple are economically central; major production in West Africa and India.

Cultural & historical context

Cashews are native to Brazil, taken by Portuguese traders to India and Africa, where they became major crops and embedded deeply in local cuisines — so much so that cashew curries feel quintessentially Indian despite the nut's American origin. The dangerous shell-processing means cashews are almost never sold truly raw in-shell, a quiet fact behind every bag.
