How to Eat Florida Stone Crab Claws

Florida stone crab claws are steamed immediately after harvesting.

They are graded by size: Colossal, Jumbo, Large, and Medium. Large claws are the most popular size.

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 To Crack Crab Claws

Crab claws are already cooked for you when you buy stone crabs at your fish market in Florida.

When cracking the claws, it's important to do so gently to avoid crushing the meat inside.

Crack the claws 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.

You can also pick up a stone crab cracker at the fish market.

This lightweight aluminum device, as shown above, simplifies the process of cracking the crabs.

Simply place the crab in the device, and gently press down on the joints. The shells will easily slip off.

How Big Are Stone Crabs?

When harvested from traps on the ocean floor, only the claws of crabs measuring at least 2 ¾ inches long are removed.

The crabs' bodies are returned to warm waters to grow back. This process takes 18 to 24 months and helps their populations.

Stone Crab Claws are Sustainable

Stone crabs are a good seafood choice. Only their claws are taken, and the crabs are put back in the water. This lets them grow back their claws.

Only claws 2 ⅞ inches or larger can be taken, and harvesting from egg-bearing crabs is not allowed.

There is a limit of 1 gallon of claws per person or 2 gallons per boat daily.

For more of the rules, visit The Florida Fish & Wildlife Commission/Stone Crab.

Mustard Sauce for Stone Crabs Recipe

The traditional accompaniment for stone crabs is a tangy mustard sauce. This sauce is simple to prepare and pairs perfectly with the succulent stone crab claws, enhancing their flavor.

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. The sauce was sweeter than usual, and it tasted great.

Where Can I Get Stone Crabs Online?

Order stone crab claws with mustard sauce online from The Key Largo Fisheries in Key Largo.

The crabs will be at your door within 24 hours.

Or, you can visit us in The Keys in October to mark the start of the stone crab season, which extends through May.

How Many Claws Per Person?

Approximately 1 ½ pounds of Florida stone crabs should generously serve two adults.

Are Stone Crabs Expensive?

According to Business Insider, stone crabs rank among the most expensive seafood items on the market.

Stone crab claws are one of the priciest seafoods you can buy. And depending on their size, a pound of claws at a restaurant can cost as much as $70. But catching these crabs is challenging work. Strangely enough, fishers can only harvest the claws from the crabs, while the bodies must be returned to the ocean. So, what makes these claws so coveted? And why are they so expensive?

Business Insider

Stone crab claws have become more expensive over the years, ranging from $35.00 per pound for medium claws to $95.00 for colossal claws.

What Size Stone Crab Claws Should I Buy?

No matter the size of the stone crab claws you choose, they all taste fantastic. Get the ones that fit your budget.

Jumbo or Colossal claws can cost more. However, I think the taste is about the same for Medium and Jumbo sizes.

Storage

If you're purchasing fresh stone crabs, place them in a plastic bag and store them in the back of your refrigerator. For maximum flavor, consume them within 24 hours.

Although they might last for three or four days, it's best to enjoy them as soon as possible.

Stone crab season runs from October 15th to May 1st. During this time, you can get stone crab claws at almost every restaurant in the Keys.

You can use special crab cracking tools, but a kitchen mallet, the back of a heavy knife, or a small hammer can work too.

Stone crab claws provide a tasty meal and show how we can enjoy seafood in a responsible way.

Their limited season, sustainability practices, and unique flavor profile make them a standout choice for a very special meal.

Where to Get Stone Crabs in Key West

Our favorite places for stone crab claws in Key West include A & B Lobster House, Blue Heaven, DJ's Clam Shack, and Eaton Street Seafood.

All the restaurants have them. They should all be pretty good. A largo claw is the same large claw across the board.

The most important thing is that they're fresh. They should be moist, sweet and very delicious.

In Miami Beach, head to Joe's Stone Crab, if you can get in. I haven't been there in years, but from what I hear, it could take a while to get a reservation.
