Soft shell crabs are one of the most celebrated delicacies of the coastal culinary world. Unlike their hard-shelled counterparts, which require mallets, picks, and a fair amount of patience to extract the meat, soft shell crabs are eaten almost entirely whole. This is because they are blue crabs that have recently molted their hard outer casing, leaving behind a tender, velvety skin that becomes crispy and delicious when prepared correctly.
However, before these crustaceans can hit the frying pan or the grill, they require a specific preparation process. While some fishmongers will clean them for you, knowing how to clean soft shell crabs yourself ensures maximum freshness and allows you to inspect the quality of your seafood. The process is surprisingly straightforward and takes only a few minutes once you master the technique.
Selecting the Best Soft Shell Crabs
The foundation of a great meal starts at the market. When you are looking for soft shell crabs, freshness is paramount. Ideally, you should purchase them while they are still alive. Live crabs should be damp, kept on ice or in a cool, humid environment, and show signs of movement.
The shells should feel soft and pliable, almost like leather or heavy parchment. If the shell feels brittle or “papery,” the crab has likely begun the “leatherback” stage, where the new shell starts to harden. While still edible, these won’t have that signature melt-in-your-mouth texture. Once you bring them home, keep them cold and prepare them as soon as possible, ideally within 24 hours.
Essential Tools for Cleaning
Cleaning soft shell crabs does not require a specialized toolkit. Most home cooks already have the necessary items in their kitchen drawers. You will need:
- A pair of sharp kitchen shears: This is the most important tool. Standard scissors will work, but heavy-duty kitchen shears provide better control.
- A cutting board: Choose one that is easy to sanitize afterward.
- Paper towels: These are essential for patting the crabs dry before cooking.
- A bowl of ice water: To keep the crabs cold if you are cleaning a large batch.
Step by Step Guide to Cleaning Soft Shell Crabs
The goal of cleaning a soft shell crab is to remove the parts that are either inedible or possess an unpleasant texture, while keeping the body and legs intact. There are three main components to remove: the face, the gills, and the apron.
Removing the Face
The first step is the most daunting for some, but it is necessary for a pleasant eating experience. Using your kitchen shears, make a single, clean cut across the front of the crab, about 1/4 inch behind the eyes and mouthparts.
By removing the “face” in one swift motion, you eliminate the eyes and the gritty mouth parts. This is also considered the most humane way to dispatch the crab if it is still alive. After making the cut, you can use the tip of your shears or your fingers to gently squeeze the area behind the cut to remove any excess fluid or the small green bag (the stomach) if it is visible.
Trimming the Gills
The gills, often referred to as “dead man’s fingers,” are located under the side points of the top shell. While they aren’t harmful if eaten, they have a tough, spongy texture and a bitter taste that can ruin a dish.
To remove them, lift one of the pointed corners of the top shell to reveal the feathery, beige-colored gills underneath. Use your shears to snip them off at the base where they attach to the body, or simply use your fingers to pull them away. Repeat this process on the other side. Once the gills are gone, press the top shell back down into its original position.
Removing the Apron
Flip the crab over onto its back. You will see a small, flap-like piece of shell known as the “apron.” On male crabs, this is narrow and shaped like a T or the Washington Monument; on females, it is wider and more rounded.
Lift this flap with your fingers or the tip of your shears and snip it off at the base. Removing the apron ensures that the entire underside of the crab is uniform and easy to sear or fry.
Final Preparation and Rinsing
After the face, gills, and apron are removed, give the crabs a very brief rinse under cold running water. Do not soak them, as the meat can absorb water and lose its delicate flavor.
Immediately after rinsing, place the crabs on a plate lined with paper towels. Pat the tops and bottoms thoroughly. Drying the crabs is a critical step; if they are wet when they hit the hot oil, they will steam instead of crisping up, and they may cause the oil to splatter dangerously.
Cooking Tips for Cleaned Soft Shell Crabs
Now that your crabs are cleaned, they are ready for the stove. The most popular method is a simple pan-fry or deep-fry. A light dusting of seasoned flour or cornstarch is all you need to create a golden, crunchy exterior.
When frying, aim for a medium-high heat. If you are using a skillet, a combination of butter and oil works beautifully. Cook the crabs for about 3 to 4 minutes per side until they turn bright red and the coating is crispy. If you prefer a lighter touch, soft shell crabs are also excellent when grilled over direct heat for about 3 minutes per side, or broiled at 450 degrees Fahrenheit until just cooked through.
The flavor of soft shell crab is sweet and briny, so it pairs perfectly with simple accompaniments. A squeeze of fresh lemon, a dollop of tartar sauce, or a light remoulade is usually all that is required. Many enthusiasts enjoy them served on a toasted brioche bun with a slice of tomato and some crisp lettuce.
Storage and Safety
If you aren’t cooking your crabs immediately after cleaning, you can store them in the refrigerator for a few hours. Wrap them loosely in plastic wrap or place them in a covered container with a damp paper towel. However, because the internal organs have been exposed, their shelf life is very short. For the best culinary results, clean them right before you plan to drop them in the pan.
Handling raw seafood always requires basic hygiene. Ensure you wash your hands, cutting boards, and shears with hot, soapy water immediately after the cleaning process to prevent cross-contamination in your kitchen.
Frequently Asked Questions
-
Can I eat the yellow stuff inside a soft shell crab?
Yes, the yellow substance found inside the body of the crab is the hepatopancreas, commonly called the “mustard” or tomalley. It functions like a liver and pancreas. Many seafood lovers consider this the most flavorful part of the crab, offering a rich, concentrated briny taste. However, if you prefer a cleaner flavor, you can gently rinse some of it away during the cleaning process.
-
Is it necessary to kill the crab before cleaning it?
The process of removing the face with kitchen shears effectively and instantly dispatches the crab. Most chefs recommend this method as it is quick and ensures the crab is as fresh as possible at the moment of preparation. If you are uncomfortable handling live crabs, you can ask your fishmonger to clean them for you at the time of purchase.
-
Can you clean soft shell crabs ahead of time and freeze them?
While you can freeze soft shell crabs, it is generally not recommended for the best texture. The freezing and thawing process can make the delicate meat mushy and the shell less crisp. If you must freeze them, clean them first, wrap them tightly in plastic wrap to remove all air, and then place them in a vacuum-sealed bag. Use them within three months for the best quality.
-
How do I know if a soft shell crab has gone bad?
Fresh soft shell crabs should have a mild, salty scent reminiscent of the ocean. If the crab has a strong ammonia smell, a slimy texture, or if the meat looks gray and dull, it has likely spoiled and should be discarded. When buying live, if the crab shows no movement at all and feels limp, it may have been dead too long to be safe for consumption.
-
Do I need to remove the sand vein like in shrimp?
Crabs do not have a “sand vein” in the same way that shrimp do. However, the green or brownish bag located just behind the eyes is the stomach, which can contain grit or partially digested food. This is typically removed or squeezed out when you cut off the face and trim the front of the crab, so no further “deveining” is required.
