Eating crab can seem a little tricky at first, but once you get the hang of it, it's a real treat. Here's a step-by-step guide to help you out:

1. Crab Claws: For cracking the legs and claws.
2. Nutcracker: For the tougher parts.
3. Fork: For extracting the meat.
4. Small Spoons or Picks: For reaching into the nooks and crannies.

Lift the shell to access the edible part. Remove the gills and inedible parts (sandbag, if present).

Use a fork to extract the meat from the internal cavities of the crab body. The meat can be in places like the legs, claws, and the main body.

Accompany the crab meat with melted butter, lemon, aioli, or other sauces of your choice.

Bread or crackers can be used to enjoy the crab meat and sauces.

You can season the crab with melted butter, garlic, lemon, parsley, or other herbs and spices to your taste. Serve the crab hot with sides like potatoes, corn, rice, or grilled vegetables. Crab can also be used in dishes such as pasta or salads.

Crab is a nutritious food, rich in protein and minerals while being low in fat, making it a healthy choice for a balanced diet.
