It's not just about throwing it in a pot of boiling water and hoping for the best. There's a real knack to it, and getting it right can mean the difference between a delicious, succulent feast and a disappointing, rubbery mess.

Over the years, I've tried countless methods, from steaming to baking, grilling to poaching, and I've learned a thing or two about the intricacies of cooking crab. It's not always easy, especially when you're dealing with different types of crab, different sizes, and varying levels of freshness. But with a bit of practice and a good understanding of the fundamentals, you too can master the art of crab cooking.

This article is your ultimate guide to mastering the art of crab cooking, providing you with all the information you need to cook perfect crab every time. From choosing the right crab to understanding the various cooking methods, I'll cover everything you need to know to impress your friends and family with your culinary prowess.

(Part 1) Choosing the Right Crab

Understanding the Different Types of Crab

First things first, you need to choose the right crab. There are literally dozens of different crab species out there, each with its own unique flavour and texture. Some are more suited to certain cooking methods than others. Here are a few of the most common types of crab found in the UK:

• Brown crab: This is the classic crab you'll find in most fishmongers and supermarkets. It has a sweet, delicate flavour and a firm, meaty texture. It's perfect for steaming, grilling, or baking. The brown crab is typically the largest and most commonly eaten crab in the UK, and its rich flavour makes it a favourite for both casual and fancy meals.
• Velvet crab: This crab is known for its sweet, slightly nutty flavour and its velvety texture. It's a great option for steaming or baking. The velvet crab is a smaller species than the brown crab, and its delicate flavour is best enjoyed with simple cooking methods.
• Spider crab: These crabs have long, spindly legs and a relatively small body. Their meat is delicate and sweet, and they're great for steaming or grilling. Spider crabs are known for their unique appearance and are a popular choice for seafood enthusiasts looking for a unique experience.
• Edible crab: This is a small, easily-cooked crab with a firm, white meat. It's often served whole, with the shell removed. You can cook it in a variety of ways, but steaming or poaching is most common. Edible crabs are a great option for smaller meals or as a starter. Their versatility and affordability make them a popular choice for home cooks.

Choosing the Right Size

Once you've chosen your type of crab, you need to consider its size. For most cooking methods, a medium-sized crab is ideal. A medium-sized crab will typically weigh between 1 and 2 pounds. This size provides a good balance of meat and shell, ensuring that there's enough meat to enjoy without the shell being too overwhelming. If you're cooking for a large group, you might want to opt for a larger crab, but remember that larger crabs can take longer to cook.

However, there are occasions when you might prefer smaller crabs, such as when you're cooking for a smaller group or when you want a more delicate flavour. Smaller crabs, usually weighing less than a pound, are ideal for individual servings or for preparing dishes where the crab is not the main focus.

Checking for Freshness

No matter what type or size of crab you choose, it's important to ensure it's fresh. Look for crabs with bright, shiny shells and eyes, and avoid those that smell fishy or have a dull, cloudy appearance. The eyes should be black and shiny, not sunken or cloudy. If the shell is dull or discolored, it's a sign that the crab is not fresh. Also, a fresh crab should have a mild, slightly sweet smell. If it smells fishy or ammonia-like, it's a sign that it's gone bad.

If you're unsure, ask your fishmonger for advice. A good fishmonger will be happy to help you choose the freshest crab.

(Part 2) Preparing the Crab

Once you've chosen the perfect crab, it's time to prepare it for cooking. This involves a few simple steps, but they're essential for ensuring your crab cooks evenly and retains its flavour.

Cleaning the Crab

The first step is to clean the crab. This involves removing any dirt or debris from the shell and removing the gills. To do this, you'll need a sharp knife and a sturdy brush. Start by rinsing the crab under cold water to remove any loose dirt. Then, use your brush to scrub the shell and the underside of the crab. Pay special attention to the area around the mouth and the gills. The gills are the feathery, dark-coloured organs located on either side of the crab's body, just under the shell. They are not edible and should be removed.

After brushing, rinse the crab again under cold water to remove any remaining debris. Next, use your knife to remove the gills. Simply pry them off with your knife and discard them. Once you've removed the gills, you can rinse the crab one last time before proceeding to the next step.

Cracking the Crab

The next step is to crack the crab. This isn't essential for all cooking methods, but it's often recommended as it helps the crab to cook more evenly and ensures that the meat is tender. This step is particularly important for boiling and steaming methods, as it allows the heat to penetrate the meat more quickly and efficiently.

To crack the crab, you'll need a crab cracker or a heavy kitchen mallet. There are different methods for cracking, but I personally find that the most efficient way is to start by cracking the legs and claws using a crab cracker, and then, if needed, use the mallet to crack the rest of the shell. Start by holding the leg or claw firmly with one hand and using the crab cracker to apply pressure to the joint. This should crack the shell and allow you to access the meat.

For the body, use a mallet to crack the shell in a few places. However, be careful not to crush the meat. Aim for a few cracks that will allow the heat to penetrate but will still allow you to easily extract the meat later.

Seasoning the Crab

Finally, you can season the crab. This is a matter of personal preference, but I like to season my crab with salt, pepper, and a pinch of paprika. You can also add other seasonings like garlic powder, onion powder, or cayenne pepper.

However, it's important to use a light hand with seasoning as you don't want to overpower the delicate flavour of the crab. Seasoning the crab before cooking allows the flavours to infuse into the meat during the cooking process. You can also add the seasonings after cooking, but it's generally recommended to season beforehand for better results.

(Part 3) Cooking Methods

Now that you've prepared your crab, it's time to choose your cooking method. As I mentioned before, there are many different ways to cook crab, and each method has its own advantages and disadvantages. The best cooking method for you will depend on your personal preferences and the type of crab you're using.

Steaming

Steaming is the most popular method for cooking crab, as it results in a tender, succulent meat. It's also a relatively simple method that doesn't require any special equipment.

To steam crab, you'll need a steamer basket and a large pot with a lid. Fill the pot with about an inch of water and bring it to a boil. Place the crab in the steamer basket and lower it into the boiling water. Cover the pot and steam for 10-15 minutes, or until the crab is cooked through. The crab is done when the shell is bright red and the meat is opaque.

To ensure even cooking, make sure that the crab is not overcrowded in the steamer basket. If you're steaming a large crab, you may need to use a larger steamer basket or split the crab into smaller pieces. Also, make sure that the water is boiling before you add the crab to the steamer basket. This will help to ensure that the crab cooks evenly and quickly.

Boiling

Boiling is a quick and easy way to cook crab, but it can make the meat slightly rubbery. To boil crab, you'll need a large pot with a lid. Fill the pot with enough water to cover the crab and bring it to a boil. Carefully add the crab to the pot and cover it with a lid. Boil for 10-15 minutes, or until the crab is cooked through. The crab is done when the shell is bright red and the meat is opaque.

To prevent the crab from becoming rubbery, you can add a few tablespoons of vinegar to the boiling water. The vinegar helps to tenderize the meat and prevent it from overcooking. Also, make sure that the water is boiling before you add the crab to the pot. This will help to ensure that the crab cooks evenly and quickly.

Baking

Baking is a great way to cook crab if you want to add some flavour to the meat. To bake crab, you'll need a baking dish and some butter or olive oil. Preheat your oven to 375 degrees Fahrenheit (190 degrees Celsius).

Place the crab in the baking dish and drizzle with butter or olive oil. Season with salt, pepper, and any other desired seasonings. Bake for 15-20 minutes, or until the crab is cooked through. For a more flavorful bake, you can add some aromatics, such as garlic, onions, or herbs, to the baking dish. Also, you can add a little bit of water or broth to the bottom of the baking dish to help create steam and prevent the crab from drying out.

Grilling

Grilling is a great option for cooking crab if you want a smoky flavour. To grill crab, you'll need a gas or charcoal grill. Preheat the grill to medium heat.

Place the crab on the grill and cook for 5-7 minutes per side, or until the meat is cooked through. The crab is done when the shell is bright red and the meat is opaque. Make sure that the grill grates are clean before you add the crab to the grill. This will help to prevent the crab from sticking to the grates and will also help to ensure even cooking.

Also, be careful not to overcook the crab. Overcooking can make the meat tough and dry. You can also grill the crab in a foil packet for a more gentle cooking method. Simply wrap the crab in foil with butter, garlic, and herbs, and then place the packet on the grill. This will create a steamy environment that helps to cook the crab evenly and prevents it from drying out.

Poaching

Poaching is a gentle way to cook crab, and it's a good option if you're concerned about overcooking the meat. To poach crab, you'll need a large pot with a lid and some poaching liquid. The poaching liquid can be made with water, wine, or broth.

Bring the poaching liquid to a simmer. Add the crab to the pot and cover it with a lid. Poach for 10-15 minutes, or until the crab is cooked through. The crab is done when the shell is bright red and the meat is opaque. Poaching is a great way to cook crab without the risk of overcooking. The gentle simmering helps to preserve the delicate flavour and texture of the crab meat. You can add some aromatics, such as onions, garlic, or herbs, to the poaching liquid to infuse the crab with flavour. Also, be sure to use a poaching liquid that is not too salty, as this can make the crab meat taste salty.

(Part 4) Checking for Doneness

It's important to check the crab for doneness to ensure that the meat is cooked through and safe to eat. There are a few tell-tale signs that indicate the crab is ready.

Shell Colour

The most obvious sign that a crab is cooked is its shell colour. The shell will turn bright red when the crab is cooked through. If the shell is still white or pale pink, it's not done yet. The change in colour is due to the heat causing the pigments in the shell to change. If the crab is still partially white, it means that the heat hasn't penetrated the shell completely, and the meat is not cooked through.

Meat Opacity

Another way to check for doneness is to look at the meat. The meat will be opaque, or white, when it's cooked through. If the meat is still translucent or pink, it's not done yet. The meat will become opaque when the proteins in the crab meat coagulate, which is a sign that it's cooked through.

You can also test the meat by using a fork. If the meat flakes easily, it's cooked through. If it's still tough, it needs to cook longer. The meat should flake easily when it's cooked through. This is because the proteins have coagulated and the meat has become tender. If the meat is still tough, it means that the crab has not been cooked long enough.

(Part 5) Serving and Enjoying

Once the crab is cooked, it's time to serve and enjoy. I find that the best way to serve crab is to crack the shell open with a crab cracker and then carefully remove the meat with a fork.

Serving Suggestions

Crab can be served in a variety of ways. Here are a few serving suggestions:

• As a main course: Serve crab with a side of rice, potatoes, or vegetables. This is a classic way to serve crab and is a satisfying and flavorful meal. You can also add a sauce, such as a lemon butter sauce or a garlic cream sauce, to enhance the flavor of the crab.
• In a salad: Add crab meat to a salad with lettuce, tomatoes, and other favourite toppings. This is a light and refreshing way to enjoy crab. You can use any type of salad dressing, but a vinaigrette or a creamy dressing is a good choice.
• On sandwiches: Make crab sandwiches with mayonnaise, lettuce, and tomato. This is a quick and easy way to use up leftover crab meat. You can also add other fillings to your crab sandwiches, such as avocado, cucumber, or red onion.
• In a dip: Mix crab meat with cream cheese, mayonnaise, and other seasonings to make a delicious dip. This is a great way to use up leftover crab meat and is a popular appetizer or snack. You can serve the dip with crackers, bread, or vegetables.

Dipping Sauces

Crab goes great with a variety of dipping sauces. Here are a few suggestions:

• Melted butter: This is a classic dipping sauce for crab. You can add a pinch of lemon juice, garlic powder, or cayenne pepper to the melted butter for extra flavour. Melted butter is a simple and delicious dipping sauce for crab. The richness of the butter complements the delicate flavour of the crab meat. You can also experiment with different types of butter, such as clarified butter or brown butter, for added flavour.
• Cocktail sauce: This sauce is made with ketchup, horseradish, and lemon juice. It's a great option for those who like a bit of spice. Cocktail sauce is a popular dipping sauce for crab. It has a tangy and spicy flavour that balances the sweetness of the crab meat. You can also add other ingredients to your cocktail sauce, such as chopped onion, garlic, or hot sauce, to personalize the flavour.
• Remoulade sauce: This sauce is made with mayonnaise, mustard, herbs, and spices. It's a great option for those who like a more complex flavour. Remoulade sauce is a French-inspired sauce that is often served with crab. It has a creamy and tangy flavour with a hint of spice. You can adjust the ingredients in remoulade sauce to suit your taste. For example, you can add more mustard for a sharper flavour or more herbs for a more aromatic flavour.

(Part 6) Storing Leftovers

If you have any leftover crab meat, it can be stored in the refrigerator for up to 3 days. It's best to refrigerate the crab meat in an airtight container. When reheating, it's important to cook the crab meat thoroughly to ensure that it's safe to eat.

However, I personally prefer to freeze any leftover crab meat. To freeze, place the meat in a freezer-safe container or bag and freeze for up to 3 months. Remember to defrost the crab meat thoroughly in the refrigerator before reheating it. Freezing crab meat is a great way to extend its shelf life. When you're ready to use the frozen crab meat, defrost it in the refrigerator overnight. You can then reheat it in a variety of ways, such as adding it to a pasta dish, a soup, or a salad.

(Part 7) Tips and Tricks

Here are a few tips and tricks for cooking crab perfectly:

• Don't overcook the crab: Overcooking crab will make the meat rubbery and dry. Check the crab for doneness regularly. Overcooked crab meat is not only unappealing in texture but also loses its flavour. To prevent overcooking, use a timer and check the crab frequently for doneness.
• Use a crab cracker: A crab cracker is a handy tool for cracking open the crab shell. If you don't have one, you can use a heavy kitchen mallet. A crab cracker makes it easier to crack the shell without crushing the meat. However, if you don't have a crab cracker, a heavy kitchen mallet can be used. Be careful not to crush the meat when using a mallet.
• Let the crab cool slightly before cracking it open: This will make it easier to remove the meat without breaking it. The heat from cooking can make the crab meat more delicate. Allowing the crab to cool slightly will help to make the meat less fragile and easier to extract from the shell.
• Use a fork to remove the meat: A fork is the best tool for removing the meat from the crab shell without breaking it. A fork can be used to gently pry the meat from the shell without damaging it. You can also use a small spoon or a crab picker to remove the meat, depending on your preference.
• Serve the crab with dipping sauces: Dipping sauces are a great way to enhance the flavour of the crab. Dipping sauces add a burst of flavour and richness to the crab meat. You can experiment with different dipping sauces to find your favourite combination.
