Selection and Cooking Tips 

Tips on Selecting and Buying Fresh Crabs:

Look for Live Crabs: When purchasing crabs, choose live ones whenever possible. They should be active, alert, and show signs of movement. Avoid crabs that appear sluggish or have a strong odour.

Check for Shell Integrity: Examine the crab’s shell for any cracks, holes, or damage. A healthy crab should have a hard and intact shell. Avoid crabs with broken or damaged shells, as they may indicate poor quality or mishandling.

Size and Gender: Male and female crabs have slightly different characteristics. Male crabs often have larger claws, which contain more meat, while female crabs have wider abdomens. Depending on your preference, you can select crabs based on gender and the part of the crab you intend to consume.

Cooking Methods for Preparing Crabs

Steaming: Steaming crabs is a popular and simple method. Place live crabs in a steamer basket over boiling water, cover, and steam until they turn bright red. Season with herbs and spices for added flavour.

Boiling: Boiling crabs is another common method. Submerge live crabs in a pot of boiling water seasoned with salt and spices. Cook for the required time based on the size of the crabs, and they’re ready to be enjoyed.

Grilling: Grilling crabs add a smoky and charred flavour. Clean the crabs, brush them with oil and seasoning, and place them on a preheated grill. Cook for a few minutes on each side until the shells turn vibrant and the meat is cooked through.

Baking: Baking crabs is a great option for stuffed crab recipes. Clean and prepare the crabs, stuff them with a flavorful mixture, and bake in the oven until the stuffing is cooked and the crabs are heated through.
