    What is ginger scallion crab?

    Ginger scallion crab stir fry (薑蔥炒蟹) is a classic Cantonese cuisine. This dish is very popular among Chinese seafood restaurants in the southern part of China like salt & pepper squid, lobster yee mein, steamed garlic shrimp and steamed whole fish. 

    In Chinese cuisine, we love to use ginger, garlic, green onion, cooking rice wine and white pepper to cook seafood. Therefore, in this ginger scallion crab recipe, the crabs are cooked with a flavorful sauce made mainly from ginger and scallions, green onions. It is simple yet incredibly tasty and full of umami flavor. This way to cook crab, allowing the natural sweetness of the crab meat to shine while infusing it with the aromatic and savory flavors of ginger and scallions.

    Most of the people deep fry the crabs first then stir fry them because it helps to lock the protein and retain the juice inside the crab. Therefore, the crab meat is soft and tender. However, some like to stir fry them without deep frying because it is easier and healthier. 

    I remembered my mom made this dish especially during crab season and Chinese New Year. I watched her prepare fresh and alive crab. Then, she cooked a delicious and flavorful crab stir fry dish. However, when it is my turn to do it myself. It’s quite a lot of preparation work and time. Now, I understand why crab stir fry dishes are expensive in the restaurants. 

    What kind of crab do you use?

    To make ginger scallion crab, typically we use whole crabs. Some like to use Dungeness crabs, blue crabs or other types of crabs. In this Chinese ginger and scallion crab recipe, I used blue crabs because it is easy to find at my local Asian markets and good price. Blue crabs don't have a lot of meat compared to king, queen and snow crabs. But, most of the blue crab I got at the store had roe.

    How do you choose a good crab to cook?

    In order to make this crab stir fry dish delicious, the flavor turned out great and enjoyable. Choosing a good crab is crucial. Always look for live crabs whenever possible. Live crabs are more likely to be fresh and have better flavor and texture than pre-cooked or frozen crabs. When the crabs claws are moving and eyes alert, they are alive and active.

    Also, check the shells for any visible damage, cracks or signs of discoloration. The shells should be firm and with no soft spots. Besides, choose crabs are larger in size because it provides more meat. In addition, male crabs have meatier claws, while female crabs are known for their flavorful roe (eggs). In this ginger scallion crab stir fry recipe, the crabs are female and have lots of roe. Lastly, avoid choosing crabs that have a strong fishy or unpleasant odor as this could spoil. 

    How do you prepare the crabs when they are alive and active?

    If they are alive and very active, refrigerate them for 1-2 hours. It helps to slow down their activity. Then, remove their claws. Cut the pointy legs. Open the shell, cut the crab in half and remove the gills, stomach. Don’t eat the gills and stomach discard them. See the video below the recipe card for details.

    What are the ingredients for ginger scallion crab stir fry?

    In this ginger scallion crab recipe, I used blue crabs, ginger, garlic, green onion, egg white, cornstarch, sesame oil, soy sauce, white pepper, cooking rice wine, water, salt and sugar.

    Preparation for the crab:

    • If the crabs are alive and very active, refrigerate them for 1-2 hours. This can help slow down their activity and make it easier to prepare them. 
    • First cut the claws, then pointy legs. 
    • After that, open the shell, take out the roe and save for later. 
    • Cut the flap at the back of the crab and cut it into half. Then, remove the gills and stomach on the shell. (Don’t eat the gills and stomach discard them.)
    • Wash and scrub the dirt and mud. 
    • The preparation of live crabs is quite a work, you can always buy some that are already prepared at Asian markets.

    Cooking the crab:

    FAQs:

    How do you know when crab is cooked?

    When a crab changes color from greenish or brown to orange red. Because the cooked crab is orange red. 

    Can I stir fry frozen crabs?


    Yes, you can stir fry frozen crabs, but meat and the flavor may not be as good as fresh crab. First, you need to thaw the frozen crab well before cooking with ginger and scallion sauce. Also, you can skip the deep frying part if you use frozen crab.

    How do you get meat out of crab?

    Use a crab cracker, lobster cracker or a heavy knife to crack open the claws and legs. Be gentle to avoid smashing the meat inside. Once cracked, you can use a seafood pick or a small fork to pull out the meat from the shell.

      So do you eat the shells and all? Isn’t it too hard? I know soft shell crabs are a thing but is it the same? Any blue crabs will work for this?

        We don’t eat the shell because it is hard, but we like to lick it because of the sauce and crab roe.
        Any uncooked crab or blue crabs can stir fry with ginger and scallion.
