What is cilantro root?
The author of the lavishly photographed and terrifically well-researched book Bangkok Street Food, Tom Vandenberghe, explains that cilantro root is relied on quite often in Thai cooking. It’s just a little less assertive in flavor than the cilantro leaves you’re accustomed to using. If you can’t get your hands on them at an Asian market, maybe you dig up one of your cilantro plants from the garden or make a trip to your local nursery and buy a plant specifically to be sacrificed for this recipe. Then just wash, scrape, and finely chop it, he explains. And if you can’t find cilantro root, no worries, use cilantro stems instead. It won’t be exactly the same thing, but it’s the next best option. Either roots or stems work to a fare-thee-well in this recipe, in which the cilantro presence is a subtle, intriguing hint rather than a whack-you-in-the-face-like-a-baseball-bat hit. There. A little cilantro root competency for you.
