Of Ancient Groves and Golden Fruit

In the mist-kissed hills of Assam, where the Brahmaputra carves its ancient path and the air carries whispers of a thousand monsoons, lies a secret that has flavored civilizations for millennia. This is the birthplace of the lemon: not merely a fruit, but a golden thread that weaves through the very fabric of human culinary evolution.

Long before the Mediterranean claimed citrus as its own, before California's groves stretched toward distant horizons, the highlands of Assam cradled the world's first lemons. Here, in this northeastern corner of India, nature conducted her most delicious experiment. Bitter orange met citron in an ancient dance of genetics, creating what we now know as the common lemon: a gift from Assam to the world.

At Irroi Kaziranga, we honor this profound legacy through our Baari: our living food forest where guests can walk among the descendants of those first golden fruits, tasting history itself.

The Serendipitous Birth of Kaji Nemu

Every great story needs its hero, and in Assam's citrus saga, that hero is the Kaji Nemu: the state fruit of Assam, born from chance and nurtured by generations of patient hands.

Picture this: a research station in Byrnihat, Meghalaya, where scientists collected seeds from Hashara village in Sivasagar district. Among countless seedlings, one emerged different. Completely seedless. Bursting with juice. Perfumed with an aroma that could transport you to grandmother's kitchen with a single breath.

This wasn't just botanical luck: this was destiny manifesting as fruit.

The Kaji Nemu defied everything lemons were supposed to be. Where other varieties hoarded their seeds jealously, this one gave freely of its flesh. Where others might last days, this golden treasure retained its vibrant color and fresh essence for an entire month. Its oval shape, longer than its cousins, seemed designed by nature herself to fit perfectly in the palm of an eager cook.

By the People, For the Land

Walk through the villages of Dirak Maithong, Chandrapur, or Kakopathar today, and you'll witness something extraordinary. Nearly 800 farmers across 300 hectares tend to groves that produce up to 30,000 lemons daily. But this isn't industrial agriculture: this is integrated pest management meeting ancient wisdom, where every tree is treated as family.

The formation of cooperative societies like CRS-Naa Dihing Nemu Tenga Unnayan Samity hasn't just changed economics: it's transformed lives. Farmers who once surrendered their harvest to intermediaries now command their own prices, their own destinies. From local fields to London markets: Kaji Nemu has traveled the world while keeping its roots firmly planted in Assamese soil.

In 2019, these lemons made their debut in Dubai, then crossed oceans to reach the United Kingdom. Each fruit carried with it the story of its homeland, the dedication of its growers, and the geographical indication tag that proclaims to the world: this is authentically, undeniably Assam.

Within Our Living Museum

At Irroi Kaziranga, our Baari serves as more than a food forest: it's a living museum of Assam's citrus heritage. Here, guests don't merely observe; they participate in a story millions of years in the making.

Our collection includes not just the celebrated Kaji Nemu, but also the Chinakaghi variety from which it descended, alongside other indigenous citrus treasures that have sustained Assamese culture for generations. Each morning, our culinary team harvests fresh lemons that will grace your table by evening: a journey of mere hours from tree to taste.

The experience transcends simple fruit picking. Watch our chefs transform these golden orbs into traditional masor tenga: the iconic sour fish curry that defines Assamese cuisine. Learn how different varieties contribute unique flavors: some lending sharp acidity, others offering floral notes, still others providing that distinctive aroma that makes Assamese cooking unmistakable.

Of Tenga, A Hundred Sours

In Assam, sour has a name. Tenga. The signature brightness that finishes a meal. The counterpoint to khar. A philosophy of balance.

Across the Brahmaputra valley and the hill corridors of the Northeast, more than a hundred citrus species, relatives, and landraces find home. A living library of tang: robab tenga (pomelo) with its rosy, honeyed pith; wild and cultivated nemu—from Kaji Nemu to round Gol Nemu—each leaf oil, each zest, a different song. Hedge-grown limes that bite. Citron cousins that perfume. Diversity, not monoculture. Abundance, not sameness.

And beyond citrus, the beloved ou tenga—elephant apple—arrives like rain. Not a citrus, yet keeper of Assam’s deepest sour. Thick petals, resinous, almost floral. Stewed into masor tenga, pounded into chutneys, slipped into lentil broths when the skies turn silver. The word tenga stretches to hold them all. A taste and a memory. A homecoming.

Ritual follows flavor. Pomelo shared at winter gatherings, salted and dusted with chili as blessings are exchanged. Lemons plucked at dawn, their leaves brushed across thresholds for auspicious beginnings. Pickles set under sun—peel, seed, and brine—quietly fermenting patience. Food as offering. Sourness as cleansing, as clarity.

At the Baari—the food forest beating at the center of Irroi Kaziranga—guests meet this citrus diversity with their senses. A guided walk that begins with rubbing a leaf between fingers—inhale the oils, read the plant by fragrance. A tasting flight: Kaji Nemu versus Gol Nemu, wild lime versus robab tenga. Acidity mapped on the tongue. Stories mapped on the land.

Then, the fire. Cook alongside our culinary team: one masor tenga finished with pomelo’s shy sweetness; another brightened by ou tenga’s deep, anchoring sour. A vegetarian tenga jhol that leans into seasonal greens. Peels candied, zests cured in salt, rinds fermented into cordial and bitters—our zero-waste practice moving from principle to plate.

For the wildlife enthusiasts, cultural curators, and design connoisseurs. For the conscious traveler who wants to taste place, not perform it. Quietly, Irroi Kaziranga stands as Kaziranga’s best address for immersive food journeys and citrus exploration—luxury as intimacy with land, culture, and craft.

Through Seasons of Taste

Agrotourism at Irroi Kaziranga means understanding that every season tells a different story. During flowering months, our Baari fills with the intoxicating fragrance of citrus blossoms: delicate white flowers that promise golden fruit to come. Guests can witness pollination in action, understanding the delicate balance that transforms flower to fruit.

As harvest seasons unfold, participate in traditional picking methods passed down through generations. Learn to identify perfect ripeness not just through color, but through touch, aroma, and that subtle give that speaks of juice-laden flesh within.

Our slow travel philosophy means you're not rushing through experiences: you're living them. Spend mornings in the Baari, afternoons learning traditional preservation techniques, and evenings savoring multi-course meals where every dish celebrates citrus in its many forms.

Of Memory and Flavor

In Assamese culture, lemons carry significance far beyond their culinary applications. They're woven into festivals, ceremonies, and daily rituals that connect people to their land. At Irroi, we share these stories alongside the fruits themselves.

Learn about Bihu celebrations where lemon leaves are used for their purifying properties. Discover how traditional medicine employs different parts of the citrus tree for healing. Understand the spiritual significance of citrus in Hindu and Assamese Buddhist traditions: knowledge that transforms a simple fruit into a bridge between worlds.

Our resident cultural guides: born and raised in villages where these traditions thrive: share stories that textbooks cannot contain. These aren't performances for tourists; these are family stories, community memories, living traditions that guests are invited to witness and, for a moment, inhabit.

The Future Growing Wild

As you wander through our Baari at Irroi Kaziranga, you're not just exploring the past: you're witnessing the future of sustainable agriculture and cultural preservation. Our food forest operates on principles that indigenous farmers have practiced for centuries: working with nature rather than against it, celebrating diversity rather than demanding uniformity.
