When the Menu Is Just a Suggestion

When the Menu Is Just a Suggestion

The first problem with foraging in Hoi An is that nobody tells you where the wild herbs actually are. Not the guides, not the cooks at the cooking schools, not even the grandmothers who sell bundles of them at the morning market. They’ll show you what a leaf looks like, and they’ll tell you what it’s called—”This is fish leaf,” they’ll say, or “This one, Vietnamese coriander”—but the patch of riverbank where it grows? That stays a secret. The second problem is that the secret is worth having.

On a Tuesday afternoon in late April, when the Thu Bon River was running low and brown and the heat was pressing down hard enough to make the pavement shimmer, a group of foragers followed a woman named Lan down a narrow path between a vegetable plot and a stand of bamboo. Lan is not a guide by trade. She’s a cook who works out of a small kitchen behind a tailor shop on Nguyen Phuc Chu Street, and she agreed to take people out only because her usual afternoon shift had been canceled. She moved fast, barefoot, occasionally stopping to point at something that looked, to most eyes, like a weed.

She pulled a stem with broad, slightly furry leaves and handed it to the nearest person. “Smell,” she said. It smelled like lime, but sharper, with something underneath that was almost medicinal. “This one you eat with clams. Not with fish. If you eat with fish, it’s too strong. It’s not good.” She didn’t give it a name. She just said it was “for the clams,” as if that settled the matter.

The River Gives, but Only if You Look

Mornings are for the market; afternoons are for the banks

Hoi An’s central market, on Tran Phu Street near the river, is the obvious place to start learning about herbs. It’s where tourists go for cooking classes, and it’s where the stalls are stacked high with mint, basil, and the long, serrated leaves of the “laksa leaf” that goes into every bowl of mi Quang. But the market is a curated version of what’s available. It’s what someone decided was worth selling. The riverbank, by contrast, is where the things that don’t have a commercial shelf life grow wild—the ones that need to be picked within hours of eating to be worth anything at all.

Lan led the group to a sloped, muddy patch about a hundred meters upstream from the Japanese Covered Bridge. The ground was slick, and the water lapped within a few feet of where they stood. She crouched and ran her hand through a tangle of plants that looked, to a casual observer, like nothing but a green mess. She pulled out a handful of tiny, heart-shaped leaves. “This is the best one,” she said. “You cannot buy this in the market. It doesn’t travel.”

She called it rau càng cua, which translates roughly to “crab claw herb,” named for the shape of the stem. It had a peppery, almost spicy taste that hit the back of the throat first and then softened into something grassy. It’s the kind of leaf that a restaurant in Hoi An would charge a premium for, if they could source it reliably—but they can’t, because it grows only along a few specific stretches of the river and only during certain months. By June, it’s gone.

That’s the thing about foraging here. The window is narrow, and the harvest is unpredictable. A guide in the nearby town of Tra Que, who works with a cooking school, later mentioned that the best patch of crab claw herb he knew was washed away in a flood in 2022 and hasn’t grown back. “Sometimes the river just takes,” he said, shrugging. He didn’t seem sentimental about it. It was just a fact of the landscape.

Not everything tastes good—and that’s fine

Back on the riverbank, Lan pulled another plant—tall, with leaves that looked almost like an elongated mint—and passed it around. Someone took a bite and immediately made a face. It was intensely bitter, with an aftertaste that clung to the tongue. “This one you use to wrap grilled meat,” Lan said, laughing at the reaction. “But only a little. Too much is not good. You will ruin the pork.” She didn’t say the name. She just said it was “for the pork.”

There was a logic to Lan’s naming system. In her kitchen, herbs are categorized not by species but by what they pair with. The fish leaf. The clam leaf. The pork leaf. The rice paper leaf (a broad, soft green used as a wrapper). It’s a pragmatic taxonomy, rooted in how the food actually works on a plate, not in botanical classification. And it’s why a foraging walk with Lan is less about learning Latin names and more about understanding a different way of reading the landscape—one where the question isn’t “What is this plant?” but “What should I eat this with?”

That afternoon, the group ended up with a pile of maybe a dozen different herbs, some tiny and delicate, others large and tough. Lan stuffed them all into a bag and led the way back to her kitchen. She wasn’t precious about them. She didn’t give instructions on how to store or preserve them. The assumption was that they’d be eaten within the hour, because that’s when they were good, and after that, they’d just be green stuff.

A Meal Made from the River

The kitchen behind the tailor shop is small and not particularly clean by Western standards. There’s a single gas burner, a large mortar and pestle, and a strainer that has seen better days. The fan doesn’t work. But the food that emerged from that kitchen, around 5:30 PM, was remarkable not for its complexity but for its specificity.

Lan made a simple clam soup with the sharp, lime-scented leaves—just clams steamed in a broth of ginger and fish sauce, with the herbs thrown in at the last second. The bitterness of the leaf cut through the richness of the broth in a way that felt intentional, as if the herb had been bred for exactly this purpose. Then she grilled thin slices of pork belly and served them with the bitter wrap leaves, a bowl of rice, and a dipping sauce made from fermented shrimp paste that smelled punishing but tasted savory and deep.

Every leaf on the table had been growing in the mud two hours earlier. And every leaf made the food taste different than it would have with the standard market herbs—not better in a conventional sense, but sharper, more specific. The crab claw herb, sprinkled over the soup, added a peppery kick that cilantro couldn’t have matched. The fish leaf, eaten raw alongside the pork, released its lime flavor only after a few seconds of chewing, which changed how the whole bite came together.

It was not a four-star meal. The kitchen was hot, the plastic chairs were sticky, and a fly kept landing on the rim of the dipping bowl. But the meal had something that no restaurant in the ancient town, no matter how well-reviewed, could offer: a direct, unbroken line from the riverbank to the plate.

What Gets Lost in Translation

Foraging walks are becoming a minor tourism genre in Vietnam, and Hoi An has its share of them. Several companies offer half-day trips that combine a market visit, a brief stop at a vegetable garden, and a cooking class. They’re fine. They teach people what a lemongrass stalk looks like and how to make a passable spring roll. But they tend to sanitize the experience—to turn foraging into a demonstration with a predictable outcome, where the wildness is removed and the herbs are laid out on a platter like props.

Lan’s walk was different because it wasn’t designed as a product. She didn’t have a set route. She didn’t have printed handouts. She changed her mind about which patch to visit based on the tide, and she admitted, midway through, that she wasn’t entirely sure the crab claw herb would be there. “Sometimes it’s gone,” she said. “Then we find something else.” There was no backup plan, no guarantee of a full basket. The whole thing operated on a logic of contingency: if the river gives, great. If not, you still walk along the bank and learn something about how a cook sees the world.

A man who runs a small homestay in Cam Thanh village, on the other side of the river, said that he’s tried for years to offer a similar experience to his guests, but he can’t find someone like Lan. “The young people don’t know the plants,” he said. “The old women know, but they don’t want to teach it. They say it’s too much trouble.” The knowledge exists, but it’s not organized into a service. It’s scattered across a handful of cooks and grandmothers who have better things to do than explain their work to foreigners.

That afternoon, the group didn’t find everything Lan had hoped for. The patch of one particular herb—she called it “the beef leaf”—had been trampled by someone, or maybe by an animal, and was too damaged to pick. She frowned at it for a moment, then walked on. No one asked what the beef leaf tasted like. It was simply unavailable, and that was that. The river took something else that day.

2 PM on the Riverbank

The walk itself started at 2 PM, which is an odd hour for foraging in tropical heat. Most tours start early, before the sun reaches full force, and they usually wrap up by lunch. But Lan works a kitchen shift that ends at 1:30, so 2 PM was when she was free. The result was a walk that happened in the hottest part of the day, when the sun came through the bamboo in slanted, heavy shafts and the mud on the riverbank was warm underfoot. It was uncomfortable. People sweated. They got bitten by small insects. They had to stop and stand in the shade of a banyan tree for several minutes while Lan waited, not impatiently, but not with any particular sympathy either.

That timing shaped the whole experience. The heat made people move slower, which made them look more carefully. When Lan stopped to point out a plant, the group stayed longer than they might have in cooler weather, because no one wanted to walk again. They stood and stared at the leaves, smelling them, asking questions. The discomfort, in a roundabout way, forced a kind of attention that a breezy morning walk might not have produced.

The worst moment came when someone accidentally stepped on a patch of wild morning glory that Lan had been about to pick. She didn’t get angry, but she did make a sound—a small, sharp intake of breath—that communicated more than words could have. She picked up the flattened stems and held them in her hand for a second, then dropped them and moved on. The morning glory was lost. It happened in an instant, and there was no fixing it.

On the walk back, Lan stopped at a small fruit stall near the river and bought a bag of mangoes. She didn’t explain why. She just added them to the bag of herbs, and later, in the kitchen, she sliced them and served them alongside the grilled pork, unannounced and unseasoned. They were perfectly ripe—sweet, not sour—and they cut through the salt and the fermented shrimp paste in a way that felt accidental but probably wasn’t. She didn’t mention them again.

That’s the thing about a foraging walk with someone who isn’t a guide. The herb that didn’t get found is as much a part of the story as the one that did. The hot, uncomfortable time of day shapes what you see. The lost morning glory, the trampled beef leaf, the fly on the dipping bowl—none of it is polished into a lesson. It’s just what happened.
