Wow à la Lao

Thip Khao’s Asian flavors begin in chef’s backyard garden

Virtually every nook and cranny in the modest space behind Seng Luangrath’s house is devoted to growing a vegetable or herb of some kind. Some are nestled into big pots. Others emerge from long rectangular plots that have supplanted the lawn or that abut the fence that lines the property. 

 I kneel down to take a closer look at a row of mint at my feet. 

“Mint comes back every year,” Luangrath tells me. “We don’t have to worry about it too much.” The mint is used in making laab, a Lao minced meat salad that showcases fresh herbs. Laab is just one of the dishes at Thip Khao, Luangrath’s 2-year-old restaurant in Columbia Heights, that benefits from what’s grown in the garden. 

Thai basil, another frequently used herb that graces many of the dishes on the menu, including laab, is found in a nearby plot where it’s grown from recycled stems rather than seeds. Because Thai basil of good quality is easy to obtain from suppliers, less space in this garden is committed to it.  

Instead, more space is devoted to growing Thai chili peppers. The two plots adjacent to the mint and Thai basil feature newly planted ones. Once picked, they’ll be used to add heat wherever it’s called for on Luangrath’s menu.  

“These have a better kick to them than the chili peppers sold at Asian supermarkets,” Luangrath says. “They not only have a different heat but more flavor.” 

Luangrath is careful to point out the distinctiveness of her chili peppers, which are red, more slender, drier and produce a more potent pith and rib of interior seeds. 

Another garden mainstay found in the rich stews at Thip Khao are kaffir lime leaves. The unique leaves, always appearing as a connected hourglass-shaped pair, are intense but more rounded in flavor than conventional limes. Obtained from a thorny tree, the leaves, sliced to release their essence, are an indispensable ingredient. 

“More and more Asian markets are carrying kaffir lime leaves now. They come refrigerated or frozen,” Luangrath says. “While that’s OK, nothing beats having fresh ones from the tree.” 

Luangrath’s kaffir lime trees are planted in pots, ones that she transfers from her greenhouse to the rear of the garden once spring has arrived. While actual kaffir limes—with their characteristically pebbly skin—are nearly impossible to grow here, the trees produce a bounty of leaves.  

“Look,” she says. “Here’s our big tree.” Luangrath shows me a large kaffir lime tree, neither dainty nor slight like the rest, with tall branches that she must stretch out to reach. Having braved fluctuations of weather and thrived for decades, this one’s become a family heirloom. 

Luangrath’s backyard garden dates back to 1993 when she and her husband, Boun, bought this house in Northern Virginia. That was 17 years before assuming ownership of Bangkok Golden, Luangrath’s first restaurant, in Falls Church—a Thai restaurant, offering mostly Thai classics, that’s still going strong today.  

There, first as specials and later on a “secret menu” whose rewards spread quickly by word of mouth and online chatter, Luangrath introduced her native Lao food to the public. It caught fire. Thip Khao followed in 2014.  
The garden—an expression of a longtime practice dating back to Laos, where Luangrath grew up—became, as circumstances dictated, a source of ingredients for the restaurants. But as a source of pride and identity, the garden would still exist even if Luangrath didn’t own two successful restaurants.  
Back in Laos, keeping a garden was a part of daily life. “Growing up, like everyone, we had a garden,” Luangrath recalls. “My grandmother would tell me to pick this herb or that vegetable from the garden when she was making dinner. And I’d go pick it fresh from the garden.”  
Luangrath also remembers having a papaya tree that allowed for the freshest papaya salad and coconut trees that supplied fresh coconut milk. The tropical weather was conducive to growing all manner of tropical fruit—ones that the climate in Northern Virginia simply can’t support.  

Luangrath had tried growing papaya, longan and guava in her garden here but to no avail. “Now, we just focus on whatever we can grow.” That focus has resulted in harvesting leaves rather than fruit.  

A betel nut tree is one case in point. Dark green and oval in shape with a sharp point, betel leaves are an integral part of a dish called mien muang luang (rice paste wraps). Luangrath uses the leaves to hold the pounded sticky rice, which is eaten by hand.  

Luangrath’s guava tree, ever fruitless, produces leaves that end up in guinea fowl soup where the long, blunted green leaves, once steeped into the broth, add a dose of umami. 

There are other flourishes in the garden as well: rows of cilantro and lemongrass, dangling strands of purple and green snake beans. Now, toward the end of the growing season, there are even occasional kabocha squash, which are green on the outside, small and squat.  

Bobby Pradachith, Luangrath’s son and a 2014 graduate of the Culinary Institute of America, came on board last year to be her co-chef at Thip Khao. He had worked most recently at Minibar by José Andrés, honing his craft and learning the finer points of molecular gastronomy.  

The chance to partner with his mom was a calling that he couldn’t pass up. It meant that he could shoulder some of the burden of running the family business but also, as a first-generation Lao-American, discover an important part of himself through the food. 

 Since his arrival, he’s become the de facto manager, supervising the front of the house, and an all-purpose specialist in the back of the house: cooking, doing prep work and, yes, thinking about how to best utilize the resources of his mom’s garden.  

Pradachith has his mom’s Thai bird’s eye chilies on his mind. And, while one would think having a plethora of actual chilies would diminish the importance of the leaves, that’s not the case.  

“They’re really cool,” Pradachith says of the thumb-sized chili leaves, which he adds to laab. “They’re kind of citrusy. And, what you taste is the essence and flavor of Thai chili but minus the spice.”  

Despite how uniquely he employs the chili leaves, it’s another type of leaf that fascinates him the most. 

“I’m kind of obsessed with ginger leaves,” Pradachith confesses.  

Ginger root is well known for its use as a spice and seasoning throughout Asia—ginger leaves not so much. The slender leaves, about a hand’s length, tapering to a gentle point, look vaguely like the head of a spear. Unlike the root itself, which is peppery and can be astringent, the leaves are mild and somewhat sweet while still possessing the essence of ginger. 

Pradachith loves how it complements fish—leaving a gentle gingery quality that’s less harsh than the flavor imparted by the root. And, unlike banana leaves, which are discarded once they are unwrapped to reveal the fish, ginger leaves soften when steamed and can be eaten. 

“I don’t see any other culture using ginger leaves,” Luangrath says. “Ginger leaves were first used in the northern part of Laos, but now it’s used throughout the country.” 

Pradachith uses mustard green flowers, with their petite yellow petals, as a garnish on the fish. “It makes the fish look good,” Pradachith says. “But it also has a slight vegetal quality, a bright floralness. It also has a bit of spiciness too because of what mustard green is.” 

Perhaps one of the most unique herbs in the garden, Luangrath points out to me last. She pauses to remember its name. “It’s called fish herb or fish mint, I think” she says.  

Luangrath takes one of its leaves and breaks it. “We don’t use it a whole lot in the restaurant,” she admits. “It’s more for personal use.” 

As I press the broken piece to my nose, the aroma wafts out and smells incredibly and distinctively of fish—amazing.
