2. Tips for Choosing Fresh West Sea Blue Crabs

Choosing fresh and delicious blue crabs is the first step to a great culinary experience. Use the following methods to select the best blue crabs.

2.1. How to Distinguish Male and Female Crabs

In autumn, plump male blue crabs are in season. You can easily distinguish male and female crabs by the shape of their abdominal flap.

• Female Blue Crab: The abdominal flap is wide and round, forming an obtuse angle (like a full moon or a broad jar). In spring, before spawning, they are full of roe, making them a good choice if you prefer roe.
• Male Blue Crab: The abdominal flap is narrow and pointed, forming a triangular shape. In autumn, they are full of meat and their sweetness reaches its peak.

2.2. How to Check Meat Yield

Checking the meat yield of blue crabs is an important indicator of freshness and taste.

• Weight: Crabs of the same size that are heavier are more likely to be full of meat.
• Legs: Crabs with plump legs that are firm when pressed are more likely to have a good amount of meat.
• Shell: If the shell is dirty, it's likely been a while since molting, meaning the crab is more likely to be fuller of meat. (While not an exact indicator of meat yield, this can be a helpful reference based on experience.)
• Checking for Roe in Female Crabs: If the side of the female crab (the part visible when the legs are pulled back) has a reddish tint, it's a sign of roe. The deeper the color, the more roe it contains.
• Vigor: Choose live crabs that are active and have all their legs intact.
• Smell: Choose those that don't smell fishy but have a distinct fresh sea scent.
• Lifting: It's best to choose one that feels heavy when lifted by hand.

3. How to Prepare and Store West Sea Blue Crabs

Proper preparation and storage are crucial for enjoying blue crabs deliciously.

3.1. How to Prepare Live Blue Crabs

1. Stunning: Live crabs are difficult to handle, so stun them by placing them in the freezer for 20-30 minutes. Alternatively, you can put them in ice water or cold water and refrigerate them.
2. Removing Impurities: Use a brush to thoroughly scrub the crab's body under running water. Open the abdominal flap, press the center part to remove impurities, and open the mouth to clean it.
3. Removing Unnecessary Parts: Cut off the pointed claws and leg tips with scissors. Remove the gills and sand sac located inside the carapace. Inserting scissors into the crab's mouth and twisting it to drain the bodily fluids can reduce fishy odors.
4. Cutting: Cut the prepared crab into 2 or 4 pieces as needed. It's convenient to prepare them when slightly frozen, as this prevents the meat from falling apart.

3.2. How to Prepare Frozen Blue Crabs

1. Thawing: Lightly rinse frozen crabs under running water.
2. Preparation: Prepare them in the same way as live crabs. Remove any visible netting and scrub thoroughly with a brush. Open the carapace, remove the gills, sand sac, and mouthpart, then rinse again under running water. Remove the claws and leg tips, cut into bite-sized pieces, and drain excess water in a colander.

3.3. How to Store Blue Crabs

• Short-term Storage (Refrigeration): Wrap each prepared crab individually or place them in a zip-top bag and refrigerate. They can be stored for about 1-2 days. Live crabs can be placed in sawdust and stored in a regular refrigerator or kimchi refrigerator to help maintain their freshness.
• Long-term Storage (Freezing): Wrap each prepared crab individually or place them in a zip-top bag, seal tightly, and store in the freezer. They can be stored for about 2-3 months. Blue crabs have a high moisture content in their shells, so a lot of water can be released when thawed. It's best to portion them into single-use amounts before freezing. They can also be lightly boiled, cooled, and then stored.

4. Popular Recipes Using West Sea Blue Crabs in September 2026

Here are various dishes you can make with plump autumn blue crabs. Experience the distinct flavors of autumn, different from Summer Food.

4.1. Steamed Blue Crab

This dish best highlights the natural flavor of blue crab.

1. Stunning and Cleaning: Place water and crabs in a bowl, add ice, and stun for 10 minutes. Cut off the tips of the crab's legs and claws, then scrub thoroughly between the legs with a brush.
2. Steaming: Place the crabs shell-side down in a pot with a little water, salt, and doenjang (fermented soybean paste), then cover and steam for 15-20 minutes. Steaming them shell-side down prevents the guts from spilling out. Adding rice wine (cheongju) to the water can eliminate fishy odors.
3. Preparation: Hold the steamed crab's belly, open the carapace, remove the gills and mouth attached to both sides of the body with scissors, then cut the body in half, and then cut each half into three pieces.

4.2. Blue Crab Stew

Cool and spicy Blue Crab Stew is perfect for the chilly month of September.

1. Ingredient Preparation: Clean and prepare the blue crabs. Slice radish and zucchini thinly, and diagonally slice green onions and red chili peppers. Cut off the bases of enoki and oyster mushrooms and tear them apart, and trim the stems of crown daisy.
2. Broth and Seasoning: Pour kelp, shrimp, and anchovy broth into a pot, add radish, and bring to a boil. Mix doenjang, chili powder, gochujang (Korean chili paste), rice wine (cheongju), minced garlic, ginger juice, and pepper to make the seasoning paste.
3. Cooking: Once the radish is cooked, add the blue crabs and seasoning paste and boil. Add the remaining vegetables and boil for another short while until done. If you boil and mash old pumpkin or kabocha squash and add it to the seasoning paste, you can add a soft, healthy sweetness.

4.3. Ganjang Gejang (Soy Sauce Marinated Blue Crab)

Ganjang Gejang, known as a "rice thief," boasts an exquisite savory flavor.

1. Preparing the Blue Crabs: Stun live blue crabs by placing them in the freezer, then clean them thoroughly.
2. Making the Soy Sauce Marinade: In a pot, combine water, regular soy sauce, soup soy sauce, mirin, ginger, whole garlic cloves, green onions, onion, apple, cheongyang peppers, dried pollock heads, etc., and boil for 20 minutes from the boiling point. Once the soy sauce mixture has boiled, strain and remove the solids. Then, add sugar, plum extract, and soju to the liquid, stir well to dissolve the sugar, and let it cool.
3. Marinating: Once the marinade has cooled, pour it over the prepared blue crabs in a container, close the lid, and refrigerate.
4. Aging: After about 2 days, take only the soy sauce marinade from the Ganjang Gejang, boil it separately in a pot, cool it down, and then pour it back over the crabs before serving for an even more delicious taste. Adding red pepper seeds during marinating can also remove fishy odors and enhance the savory flavor.
