How to Eat Stone Crab Claws
Stone crabs are steamed immediately after harvesting.
They are graded by size: Colossal, Jumbo, Large, and Medium.
The claws are cracked just before serving in the restaurants. When purchasing stone crabs at the fish store, the fishmonger can neatly crack them for you.
Just bring them home, refrigerate, and enjoy them within 24 hours.
How Do I Crack Stone Crabs at Home?
The claws are already cooked for you when you buy stone crabs at your fish market.
You can bring them home uncracked and crack them open with a stone crab cracker, nutcrackers, a stone crab mallet, or a big knife.
To use a big knife, place the flat side of a chef's knife on the flat side of the claw and press down a few times as if you are smashing a clove of garlic.
If you're buying fresh stone crabs, place them in a plastic bag and refrigerate them in the back of the fridge. Consume them within 24 hours for maximum flavor.
You can pick up a stone crab cracker, a lightweight aluminum device (shown above) when you pick up your stone crabs from your fish market.
This is an appliance that will crack the crabs with ease. Place the crab in the device, as shown, and lightly press down on the joints. The shells will slip right off.
How Big Are Key Largo Stone Crabs?
When harvested from their traps on the ocean floor, the claws are pulled from crabs that measure at least 2 ¾ inches long, and their bodies are thrown back into the warm water to regenerate (it takes 18-24 months to grow back) and maintain their populations.
How to Make Mustard Sauce for Stone Crabs
The traditional sauce for stone crabs is a tangy mustard sauce. The sauce is easy to make and goes perfectly with the dreamy stone crab claws.
Mix all ingredients in a medium-sized bowl:
- Mayonnaise
- Dijon mustard
- Worcestershire sauce
- Lemon Juice
- Horseradish
- Salt
You can also add a spoonful of sugar. We had stone crabs at a local club a few months ago and the sauce was a little sweeter than usual and it tasted very good.
Where Can I Get Stone Crabs Shipped To Me?
You can purchase stone crab claws with mustard sauce online from The Key Largo Fisheries in Key Largo and the Eaton Street Seafood Market in Key West.
The crabs will arrive in one day packed on dry ice. Of course, you can also come to the Keys in October for the start of stone crab season and runs through May.
The succulent meat is a real delicacy. One and a half pounds should generously feed two adults.
Are Stone Crabs Expensive?
According to Business Insider, stone crabs are one of the most expensive seafood items you can buy. At $30.00 per pound for medium claws and up to $95.00 for colossal claws, the prices of stone crab claws have been steadily climbing over the years.
What Size Claws Should I Buy?
Whichever size stone crab you choose, they all taste great. Buy the ones you can afford. Your meal can get very expensive if you insist on the Jumbo or Colossal size, claws, and the taste, to me, is not different from Medium to Jumbo.

The mustard sauce is not on the Kaufmann and Paleo diets. Enjoy stone crabs with a squeeze of lemon and melted Kerrygod butter on the side. They're still great!
