Foolproof Guide to Choosing and Cleaning Male Blue Crabs

Choosing fresh, meaty crabs with a 'good yield' (high meat-to-shell ratio) is the most important step. Check the criteria below and follow the simple cleaning instructions.

How to Choose Good Crabs

• Weight: Feels heavy for its size.
• Belly: The apron (belly flap) should be white and firm (a mushy one may indicate less meat).
• Legs: All legs are attached and moving actively.
• Carapace (Top Shell): Shiny, hard, and has a darkish hue (a sign that it has been a while since molting, meaning the crab is full of meat).
• Sexing the Crab: A pointed, long triangular apron indicates a male crab, while a round, wide one indicates a female.

Basic Cleaning Steps

1. Stun the Crab: Soaking the crab in ice water for 10 minutes will stun it, allowing for safe handling. You can also soak it in plain water for 20-30 minutes.
2. Wash: Use an old toothbrush or a kitchen brush to scrub the carapace, belly, and between the legs to remove any debris, then rinse under running water.
3. Remove Guts and Gills: If preparing for soups or salads (not steaming), you must separate the carapace, and remove the grey gills on both sides of the body (which cause a bitter taste) and the black sand sac inside the carapace (which causes a gritty taste).

10-Minute Prep, 20-Minute Cook! Steamed Blue Crab Recipe

Steaming is the best way to enjoy the natural sweetness of blue crabs. Adding a little doenjang (soybean paste) and cheongju (rice wine) will create flavorful steamed crabs without any fishy smell.

• Ingredients: 4 blue crabs, 1.5L water, 1 tbsp doenjang (soybean paste), 3 tbsp cheongju (rice wine) or soju

1. In a pot, combine water, doenjang, and cheongju, stir well to dissolve, and turn on the heat.
2. When the water boils and steam rises, place a steamer basket inside. Arrange the cleaned crabs with their bellies facing up. This prevents the tomalley and juices from leaking out.
3. Close the lid and steam over high heat for 15 minutes.
4. After 15 minutes, turn off the heat and let it rest with the lid on for 5 more minutes. Be careful not to open the lid while steaming, as this can create a fishy smell.

How to Use and Store Leftover Crabs

If you have leftover steamed crabs, you can freeze them and enjoy them in other dishes later.

• Freezing: Let the steamed crabs cool, then store them in an airtight container or a zipper bag in the freezer. It is recommended to consume them within one month to maintain flavor. Avoid repeated freezing and thawing, which can intensify the fishy smell, so store in single-serving portions.
• Crab Shell Bibimbap: Mix warm rice, seaweed flakes, and sesame oil with the leftover tomalley in the crab shell for a savory treat.
• Crab Ramyeon: Add frozen steamed crab when cooking ramyeon to make the broth deeper and more refreshing. A little doenjang can help remove any fishy smell and add a savory depth.

Frequently Asked Questions (FAQ)

Q. When is the closed season for blue crabs? A. The closed season for blue crabs in most areas of the West Sea is from June 21 to August 20 each year. Crab fishing is prohibited during this period. Therefore, crabs caught from August 21 are the first autumn crabs of the season. (However, in some areas like Yeonpyeong Island and the five West Sea islands, the period is from July 1 to August 31.)

Q. Why should crabs be placed belly-up when steaming? A. As the crab cooks, the delicious tomalley and juices inside become liquid. Placing the crab belly-up, with the carapace facing down, ensures that these juices collect in the shell, so you can enjoy every last drop without any loss.

Q. I'm afraid to handle live crabs. Are there other methods? A. Soaking them in ice water for just 10 minutes is the most recommended method as it's simple and safely stuns them. If you steam live crabs directly, they may struggle in the heat, causing their legs to fall off and their innards to burst, which can diminish the flavor.
