India Before Cashews

Kaju katli — India's most gifted Diwali sweet — is made from a Brazilian nut. The cashew arrived as an afterthought to a Portuguese alcohol industry, took root on the Konkan coast, and then did something extraordinary: it replaced the richness system that Mughal court cooking had developed over centuries. A nut the subcontinent had never seen became one of its most defining ingredients.

A World Before Cashews

Today cashews are so embedded in Indian cooking that it is difficult to imagine the cuisine without them. Korma, shahi paneer, kaju katli, cashew rice — the nut appears across both savoury and sweet traditions as if it had always been there. Yet the civilisations of India, Persia, Arabia, China, Greece, and Rome all developed sophisticated cuisines without cashews. The nut existed only in South America until the sixteenth century, when Portuguese traders encountered it in Brazil.

When the Portuguese brought cashew plants to their colony at Goa in 1510, they were not thinking about korma. They were thinking about the cashew apple — the swollen false fruit — which could be fermented and distilled into feni, a potent spirit. The culinary use of the cashew nut developed later, as processing knowledge spread and the nut's extraordinary culinary properties became apparent. The most famous Indian cashew product emerged as an afterthought to an alcohol production industry.

Richening ingredients before cashews — coconut, melon seeds, white poppy seeds, almonds

Richness before cashews: coconut cream, melon seeds (magaz), white poppy seeds (khus khus), and almonds — the ingredients that provided body and creaminess in Indian gravies for thousands of years before a Brazilian nut arrived.

What the Archaeology Tells Us

Historical Evidence at a Glance

Pre-1500: Cashews confined to South America. Completely absent from any Indian text, recipe, or archaeological record before Portuguese contact.

Ancient Indian texts: Coconut, melon seeds, and poppy seeds documented as richening agents in Sanskrit culinary literature. Almonds referenced as luxury thickeners in royal cooking contexts.

1510: Portuguese establish Goa. Cashew trees introduced for cashew apple production. Goan feni production begins as primary application.

1600s–1700s: Cashew cultivation expands along India's western coast. Culinary use develops gradually as processing knowledge spreads beyond Goa.

1800s: Cashew enters Mughal-influenced North Indian cooking. The nut-cream gravy tradition begins shifting from melon seeds and poppy seeds to cashews.

The Strange Biology of the Cashew

The cashew is botanically unusual in ways that explain why it required Portuguese industrial knowledge to make it usable as a food. What we call the cashew nut is not botanically a nut at all — it is a seed attached to the outside of the cashew apple, the swollen false fruit of the cashew tree. The seed sits in a double shell containing cardol and anacardic acid, both caustic oils that cause severe skin burns and must be completely destroyed by heat before the cashew is safe to eat.

This is why raw cashews are never sold commercially — all cashews on the market have been processed to remove the toxic shell oil. The Portuguese, with their experience of processing tropical products from Brazil and West Africa, understood how to manage this process. It is part of what made the introduction to India feasible. Without the processing knowledge the Portuguese brought, the cashew would have remained a curiosity rather than a food.

"The Portuguese came to Goa for India's black pepper. They brought cashews as a by-product of their Brazilian colony. The nut they barely noticed transformed Indian cooking more completely than the spice they came to buy."

Before Cashews: The Great Thickening Traditions

The roles that cashews now fill in Indian cooking — richness in gravies, creaminess in sauces, texture in sweets, garnish on rice dishes — were performed by other ingredients for thousands of years. Understanding these pre-cashew thickening traditions reveals a more complex and regionally varied world of Indian sauce-making than the cashew-cream gravies that now dominate restaurant menus.

Ingredient	Region	Role	Status Today
Coconut milk and cream	South India, coastal regions	Richness in curries	Still dominant in South India
Melon seeds (Magaz)	North India, Mughal cooking	Gravy thickener, creamy paste	Declining; largely replaced by cashews in restaurant cooking
White poppy seeds (Khus khus)	Bengal, North India	Creamy paste base, thickener	Declining; still used in traditional Bengali cooking
Almonds	Royal and festive cooking	Luxury thickener	Surviving in premium preparations
Gram flour (Besan)	Rajasthan, Gujarat	Gravy body without fat	Still widely used in kadhi and regional preparations
Sesame paste	Regional cooking	Richness and body	Surviving in specific regional preparations

Coconut was the most important pre-cashew source of richness across coastal India. Coconut milk and cream provided the body and creaminess in South Indian curries that cashews now supply in Mughal-style North Indian dishes. A properly made Kerala fish curry or Chettinad chicken curry, built on freshly ground coconut with its natural fat content, achieves a richness and depth that cashew cream cannot replicate — and the tradition is still alive.

Melon seeds (magaz) and white poppy seeds (khus khus) were ground into pastes to thicken and enrich gravies in the cuisines that eventually became most associated with cashews — the Mughal-influenced cooking of North India. These pastes appear in historical recipes where cashews are now commonly substituted. A shahi korma made with poppy seed and melon seed paste has a distinctly different texture and flavour from the cashew version — more delicate, more subtly nutty.

The Science of Richness — Why Cashews Succeed

Fat content: Cashews contain approximately 44% fat — primarily monounsaturated — providing richness without the saturated fat dominance of coconut.

Protein emulsification: Cashew proteins create a stable emulsion when ground — preventing sauces from separating under heat. Coconut cream lacks this protein-based stability.

Neutral flavour: Unlike coconut (distinctly tropical) or poppy seeds (slightly floral), cashews provide richness without adding a pronounced flavour of their own — making them ideal for restaurant-style cooking where consistency matters.

Smooth texture: Soaked cashews grind to an exceptionally smooth paste — smoother than melon seeds or poppy seeds — producing the silky gravy texture that defines the North Indian restaurant style.

Restaurant reliability: Cashew cream behaves predictably under heat across different cooking conditions. Coconut cream and poppy seed paste require more careful handling and are more prone to splitting.

Before vs After: The Richness System

Before Cashews

Coconut cream — South Indian richness, saturated and tropical

Melon seeds — delicate, subtle, Mughal-tradition thickener

White poppy seeds — creamy, slightly floral, Bengali tradition

Almond paste — luxury richness, royal context

Richness varied by region and ingredient

After Cashews

Cashew cream — neutral, stable, reliable

Cashew korma — the restaurant standard

Cashew gravy base — dominant in North Indian restaurant cooking

Kaju katli — national festival sweet

Richness increasingly standardised across regions

Regional Impact

Goa

First point of entry. Cashew feni — the distilled spirit from cashew apple — remains a protected geographical indication product and a defining element of Goan culture. The culinary nut use developed here first.

Karnataka (Coastal)

Centre of India's cashew processing industry. Dakshina Kannada and Udupi process enormous quantities for domestic use and export. The industry employs thousands, predominantly women.

Kerala

Major cashew cultivation and processing. Kerala's cashew processing workforce was historically significant in the early 20th century. Yet in cooking, coconut still dominates over cashew for richness.

Hyderabad

Nizami royal cuisine adopted cashews as a luxury thickener. Hyderabadi biryani's richness and the city's korma tradition helped spread cashew-cream cooking northward into the broader restaurant tradition.

North India (Restaurant)

Cashew korma, shahi paneer with cashew gravy, and other nut-cream preparations define the North Indian restaurant style globally. Melon seeds and poppy seeds have been largely displaced here.

All India — Diwali

Kaju katli is arguably the most universally gifted Indian sweet — thin, diamond-shaped, made from cashews and sugar. A national festival tradition built on a Brazilian nut.

Debate & Myths

Did the Portuguese Introduce Cashews for Food or for Feni?

The historical evidence suggests the primary motivation was the cashew apple rather than the nut. The Portuguese had encountered cashew apple fermentation in Brazil and recognised its commercial potential. Goan feni production — the distillation of fermented cashew apple juice — became an established industry relatively quickly after the Portuguese arrival.

The culinary use of the cashew nut developed more slowly and appears to have spread from Goa outward as processing knowledge (how to safely remove the toxic shell oil) became more widely known. The irony of this sequence — that one of India's most beloved ingredients arrived as a by-product of alcohol production — is genuinely interesting, and the historical record is fairly clear that feni, not food, was the original purpose.

Is Cashew Korma Authentic Mughal Cooking?

No — and this matters for understanding what the original Mughal culinary tradition actually was. Cashews arrived in India in 1510 and took several centuries to spread beyond Goa into North Indian cooking. The Mughal Empire's peak court cuisine — under Akbar, Jahangir, and Shah Jahan in the 16th and 17th centuries — predates the widespread use of cashews in North Indian cooking. The original Mughal nut-cream gravies were made with melon seeds and poppy seeds, possibly almonds for luxury preparations.

What is now called "Mughal cuisine" in restaurants — cashew-cream korma, shahi gravies — is a later synthesis that incorporated a Portuguese-introduced nut into a cooking tradition that predated the cashew's arrival. The flavour is different from the original. Whether it is better is a matter of preference.

What If Cashews Never Came to India?

Without cashews, melon seeds and poppy seeds would remain the primary gravy thickeners in North Indian cooking, and coconut would remain unchallenged in the south. The rich nut-cream korma that defines Indian restaurant cooking globally would taste different — more delicate, slightly more complex, with the specific flavour profiles of melon seed or poppy seed paste rather than the neutral creaminess of cashew.

Kaju katli would not exist, and Indian Diwali gifting culture would be built around a different sweet. The cashew processing industry of Karnataka and Kerala — which employs hundreds of thousands of people — would not have developed. The global trade in Indian cashews, which makes India one of the world's largest cashew exporters, would not exist.

What Survived

The Pre-Cashew Richness Tradition That Remains

Coconut — The pre-cashew richness tradition survives completely in South Indian cooking. Kerala, Tamil Nadu, coastal Karnataka, and Goa all use coconut as the primary source of richness — unchanged for thousands of years.

White poppy seeds (khus khus) — Survives in traditional Bengali cooking, particularly in posto dishes. Aloo posto and similar preparations preserve the pre-cashew poppy seed richness tradition directly.

Melon seeds (magaz) — Still available in Indian spice markets and used by traditional cooks who know the old Mughal recipes. Increasingly rare in restaurant contexts.

Goan cashew feni — The original purpose of cashew introduction to India survives as a distinct and protected geographical indication product. A direct link to the Portuguese origins of the cashew's Indian story.

Modern Legacy

Modern India and cashews — kaju katli, cashew processing, the festival sweet and the gravy tradition

Modern India: kaju katli at Diwali, cashew korma in restaurants, cashew processing on the Karnataka coast — a Brazilian nut, five centuries after arrival, completely at home.

India today is one of the world's largest cashew producers and exporters. The nut that arrived as a Portuguese by-product now defines some of India's most beloved foods — kaju katli at Diwali, korma at restaurants, cashew rice at festivals. Its adoption was slower than the chilli and more geographically specific than the potato, but it was ultimately just as complete.

The coconut-rich gravies of Kerala and the poppy-seed traditions of Bengal survive as living evidence of what Indian richness tasted like before a Brazilian nut arrived on a Portuguese ship and made itself at home. They are not relics. They are parallel traditions — equally valid, differently flavoured — that remind us that cashew creaminess is an addition to Indian cooking rather than its foundation.
