Cantonese Ginger Scallion Lobster (Cong Jiang Chao Longxia, 葱姜炒龙虾)
Published Sep 12, 2024
Does This Cantonese-Style Dish Have Boston Roots?
Mom and I are taking a detour from our usual Jiangnan recipes today to share our most beloved Chinese-American dish: Ginger Scallion Lobster.
If you’ve never heard of ginger scallion lobster (cōng jiāng chǎo lóngxiā, 葱姜炒龙虾), maybe you’ve heard of Cantonese-style lobster—they are the same thing. Yes, some version of this dish probably originated in the banquet halls of Guangdong or Hong Kong (the techniques involved are classically Cantonese), but I’d argue that the version most of us know and love was probably invented in Boston, Massachusetts.
Culinary history is often speculative, so I don’t have definitive proof to back up my theory, but consider this evidence:
- The lobster species of vermilion-shelled fame, Homarus americanus, is endemic to Northeast North America, ranging from Labrador to New Jersey. It’s also widely considered the most delicious lobster species on earth (it’s that cold water!). In China, the native lobsters belong to the Panulirus genus and inhabit tropical and subtropical waters. I’ve had many Panulirus lobsters in China, and they’re just not as flavorful (and that’s not just my Bostonian pride talking).
- Boston’s Chinatown was established in the 1870s (when workers from Guangdong were first brought over from San Francisco, in order to break up labor strikes), so the city easily has the largest Cantonese population living in an area where Homarus americanus are fished—and abundant.
- I remember the days when all the seafood restaurants on Tyler Street in Boston’s Chinatown advertised “3 for $10 Ginger Scallion Lobster” in their windows, and that seems like real “we invented this” energy.
I rest my case.
Anyways, even though neither of my parents grew up with this dish, it very quickly became the centerpiece for all family birthdays when we moved to Boston. And we didn’t get it at the Chinatown restaurants—we discovered it was even cheaper to drive up to Maine, buy “bugs” directly from the lobstermen and make it ourselves.
We also ate lobster “the American way” a few times on those trips to Maine. Verdict: A lobster roll makes a nice snack when one is outside, between a bike and a beach, and a steamed lobster with drawn butter is an enjoyable novelty (but keep that ridiculous bib away from me). Later on, I tried grilled lobster and lobster sashimi, both of which sound better than they are. I’m now a weary prodigal daughter ready to come home to Boston: ginger scallion lobster beats them all.
Yes, to make this dish, you will have to butcher live lobsters. If it’s your first time, I can promise an empowering learning experience. Your reward is the best goddamn seafood dish in the world. After the easy spoils of claws and tail, you’ll want to suck the knuckles and lick the crevasses. You’ll even want to drain the juice from the frilly gills, treating the carcass as if it were a messy marine mango pit.
Shopping For and Butchering Lobsters
New Englanders know that “shedders”—the soft-shelled lobsters of summer—have sweeter and more tender meat than the lobsters harvested in other seasons. I think their shells are also much easier to butcher. The bigger the lobster, the fewer lobsters you’ll have to butcher, so look for “quarters “(1.25 lb) or “halves” (1.5 lb). At these sizes, you can budget one lobster per person.
Live lobsters should be stored in the crisper, where they can survive 3–4 days. Remove all the packaging the lobsters came with, including bags and ice. (Perhaps obviously, also remove everything else in the crisper!) Don’t take them out of the fridge until you’re ready to take up the knife; they are sluggish when cold and easier to handle.
Prep for butchering by making sure your knife—I recommend a Western-style chef’s knife—is sharp. Then, place a dish towel under and around your cutting board to help stabilize the board and sop up liquid, since lobsters release a lot of saltwater. I also recommend wearing work gloves so you can better grapple the lobster without hurting yourself on its spiky bits.
- Place your drowsy lobster onto the cutting board and kill it swiftly by plunging the tip of your knife into its head, an inch behind its eyes. If the slippery shell makes you nervous, you can flip it over and stab it in the same spot from below instead (my preferred method). It’s normal for them to continue twitching after this initial cut, so try not to be alarmed.
- Twist off the lobster’s claws from where they connect to the carapace.
- Twist off the lobster’s tail from its carapace.
- Split the carapace in half lengthwise. (Even though the carapaces don’t have much meat, I like to include them in my stir fry because they add a ton of flavor. If you don’t want to use them, or not all of them will fit in the wok, I recommend reserving them for lobster stock—they can be frozen for months).
- Lay the tail flat on the cutting board, and slice it in half crosswise.
- Cut each piece of the tail in half again, lengthwise.
- Twist off the claws from the knuckles.
- Remove the rubber bands from the claws and use the flat of your knife, a mallet or a meat tenderizer to crack the claws and knuckle pieces.
Cooking Tips for Ginger Scallion Lobster
Once the lobsters are butchered, they’re fried in a little breading, then stir-fried in an aromatic mixture of ginger, scallions, ground white pepper and vadouvan curry powder.
You may be tempted to skip the flouring and frying steps—don’t. The little fried floury bits are essential for drawing the sauce into the lobster meat, and they make two lobsters feel like four.
This recipe is a family one, and it emulates what is served in restaurants in Boston’s Chinatown with the addition of vadouvan curry—my own twist on the dish. Vadouvan is a mild, sweet curry blend from French India, and its hybrid heritage makes it super versatile (as many, many Top Chef contestants have demonstrated). I’m not trying to be some Jean-Georges Vongerichten copycat, but I really think vadouvan’s toasty alliums, warm spices and slight smokiness marry perfectly with this dish. Give it a try.

Cantonese Ginger Scallion Lobster (Cong Jiang Chao Longxia, 葱姜炒龙虾)
Ingredients
- 2 live lobsters, between 1.25 and 1.5 pounds each, softshell preferred
- 7 generous slices of ginger
- 3 scallions, cut into 1-inch sections, whites and greens separated
- ½ teaspoon kosher salt
- ½ cup all-purpose flour
- 2 tablespoons cornstarch
- 2 cups plus 2 tablespoons frying oil, such as canola
- ½ teaspoon ground white pepper
- 1-2 tablespoons vadouvan curry (optional)
- 2 tablespoons Shaoxing wine
Instructions
- Kill the lobsters with a decisive knife plunge to the head. Butcher the lobsters by splitting them in half lengthwise, separating the claws and tail from the body, cracking the claws and knuckles, and chopping the tail into quadrants. See photos and detailed instructions in the text. Don’t throw away the body and carapace, including the gills and tomalley—they add so much flavor to the sauce!
- Mix the salt, flour and cornstarch together in a shallow dish. Dredge the lobster pieces in the mixture, focusing on coating all exposed meat.
- Bring two cups of frying oil to 350℉ in a frying pan or wok and fry the lobster pieces in batches: Lay a few pieces in the oil, being careful not to crowd them, and fry for 10 seconds (or until the shell turns red), then flip them and fry for another 10 seconds. Remove the pieces from the wok, setting them on a rack or a paper towel.
- Repeat with the remaining pieces of lobster until all are cooked; set all aside.
- Clean the wok (if you’ve used it for frying). Heat the remaining 2 tablespoons of oil over medium-high heat, then add the ginger and the scallion whites and sizzle them until they are aromatic and slightly shriveled.
- Add the white pepper, vadouvan curry (if using) and the chopped lobster pieces to the wok and stir-fry everything together vigorously for a minute, until the lobster pieces are covered in the infused oil.
- Add the Shaoxing wine by pouring it down the sides of the wok, then cover the wok and let the lobster steam for 2 minutes. Uncover the wok and stir-fry everything again for another minute. If the pan looks dry, add two tablespoons of water, since you want some sauce clinging to the pieces. Check for doneness: lobster meat should pull away easily from the shell and be firm and opaque throughout. If the meat looks shriveled, it’s overcooked! If the meat needs to cook longer, re-cover the wok and cook for another minute.
- Once the lobster is cooked through, turn off the heat and add the scallion greens, then continue to toss the ingredients together in the wok to let the carryover heat wilt them. Serve and eat the dish immediately.

A wonderful creative recipe writing piece!
Loved reading it ❤️
Thanks for letting us know!
greetings from boston! very fun to see these recipes come through and a little representation of our mighty chinatown! one thing worth noting – here in boston chinatown i have found that it is pretty common to be given the choice of either the ginger/scallion version OR a black bean version made with douchi. i had never really considered the ginger scallion version to be more common than the black bean version – i think most cantonese restaurants offer both – though perhaps i am mistaken. i made a pretty solid attempt at it years ago – i think i adapted a grace young recipe for black bean crab. the black bean sauce is pretty similar (if not identical) to clams with black bean sauce (also a staple of boston chinese cuisine given our local clams, though i think that one is a pretty direct output from hong kong) though i think some variations give the lobster version a thinner version of the sauce than the clams get.
Thanks, Josh, for this additional, interesting info!
