Cracking open a freshly cooked crab or lobster reveals a colorful interior with white meat and potentially some greenish material. This green substance naturally prompts the question – what is that green stuff inside crabs and lobsters? The answer provides insight into the biology of these delicious crustaceans.
The greenish stuff is the crab or lobster’s digestive gland, called the tomalley or hepatopancreas This organ serves multiple functions comparable to the liver and pancreas in vertebrates The tomalley produces and secretes digestive enzymes to break down food in the crustacean’s stomach. It also filters out toxins and stores energy reserves.
The green color comes from concentrating digestive enzymes as well as fat-soluble pigments from the shellfish’s food The tomalley appearance can range from yellow to dark green depending on diet and season, This gland sits in the upper midsection of the crab or lobster’s body
Is the Green Gland Edible?
The crab tomalley is edible with an intense flavor often described as creamy or buttery. Some seafood lovers consider it the tastiest part The tomalley also contains concentrated nutrients including vitamins, minerals and healthy fats.
However, there are also potential safety issues with eating this organ. As a filter for toxins, the tomalley can accumulate significant levels of environmental contaminants if the shellfish comes from polluted waters. The most concerning toxins are PCBs, dioxins, pesticides and heavy metals.
State health departments offer guidelines based on testing local harvest waters. For crabs and lobsters from relatively clean sources, authorities generally approve eating small amounts of tomalley. They warn against eating any tomalley from more contaminated areas. Cooking reduces but does not eliminate toxins.
How to Eat the Green Gland
Those comfortable with the risks have a few options for safely enjoying crab or lobster tomalley. Be sure to buy shellfish harvested from approved waters without excessive pollution. Recommendations typically limit consumption to 6 locally caught crabs per week.
The tomalley can be scooped directly from the crab body into dishes like sauces, bisques and butters. Mixing the concentrated flavor with other ingredients dilutes potentially high toxin levels. For a simple preparation, add chunks of tomalley to flavored butter.
Some cooks boil or steam the whole tomalley before eating to further reduce contaminants. But high heat also impacts the texture and flavor. Gently cooking the separated gland may provide a better experience.
What About Female Crabs?
Checking for the green crab tomalley also reveals the crustacean’s sex. Male crabs have a narrow, T-shaped apron on the abdomen while females have a broad apron shape to cover reproductive organs. A female crab may contain additional edible orange material – the roe or eggs.
Roe has a grainy, cottage cheese-like texture when raw. Cooked roe becomes firmer with a flavor described as rich and sweet. This crab caviar rivals fish roe for popping briny goodness. The roe also provides an excellent source of nutrients to support developing crabs.
Egg-bearing females must be harvested during limited seasons. Regulations enforce seasonal closures in many areas to allow reproduction and sustain healthy crab populations. Make sure to check local rules about harvesting egg-bearing females.
Cooking and Eating Crabs
The sought-after meat in crab legs and claws comes from muscles that control movement. Cooks target tasting the sweet flesh by either boiling or steaming whole live crabs. This gently coagulates proteins and loosens the meat for easy picking.
Carefully rinse live crabs before cooking. Boiling water with aromatics like spices and lemon makes a flavorful broth. Steaming over a combination of water, wine and seafood stock also imparts delicious notes.
Use a large pot to cook multiple crabs at once. Cooked crabs turn bright red with opaque white meat. Overcooking makes the flesh dry and chewy. Check larger crabs after about 12 minutes.
Let cooked crabs cool briefly before cracking open the shell. Use mallets or specialized cutters to access every bit of tasty meat in the body, claws and legs. Dip in butter or sauce between decadent bites of these briny delights from the sea.
The greenish gland inside a cooked crab or lobster certainly piques curiosity. This organ provides the biology for the crustacean to eat and filter food. While the tomalley offers intense, unique flavor, it also requires caution regarding potential toxins. Carefully sourced shellfish and moderation provide keys to safely enjoying the green crab stuff.
With sweet meat and salty ocean essence, crab offers a quintessential seafood experience. Knowing what’s inside and how to prepare them provides part of the joy of eating these delicious creatures. So gather family and friends for a feast to crack into these special treats from the sea.
