For thousands of years, all forms of seafood have been an integral component of the human diet, long before we had drawn butter to accompany our lobster meals and cocktail sauce for giant shrimp dipping. Back then, seafood was not fancy by any means; it was just food, healthy, and abundant!

Seafood has become more of a luxury item in recent years, making it less likely to appear on your weekly grocery list. A seafood dinner has become associated with special occasion meals, whether it’s king crab legs, cedar plank salmon, or frutti di mare pasta. That doesn’t mean it shouldn’t make an appearance in your kitchen now and then!

Mussels are one form of shellfish that ideally balances cost and flavor. Apart from their color, green and black mussels are two of the most prevalent varieties and have significant characteristics. Let’s learn all we can about these two creatures!

What Are Mussels?

Mussels are a kind of shellfish known as bivalve mollusks, which means they have a soft body surrounded by two shells connected by a hinge. Clams and oysters are also included in this category. Certain mollusks, such as scallops, utilize this hinge to repeatedly open and shut their shells as a means of propulsion. Some bivalves, such as mussels, prefer to remain immobile and will settle on any appropriate anchor, such as a rock, another shell, wood, or other detritus.

Mussels consume by filtering the water around them through their bodies, collecting algae and other pieces of food items as they go. As a result, bivalve mollusks are commonly recognized as ecologically benign due to the way they successfully clean the water in which they live, eliminating and using small particles that would otherwise contaminate the water.

There are many distinct species of mussels, but only a tiny percentage of them are commonly used as food. Although mussels may be found in the wild, the majority of mussels sold in restaurants, grocery shops, and fish markets come from shellfish farms.

Differences Between Green and Black Mussels

Green mussels, also known as green lipped mussels, are a species of Perna canaliculus, while black mussels are any of many other kinds of mussels, including Choromytilus meridionalis and Mytilus trossulus (which is actually technically a blue mussel, but is often referred to as a black mussel).

Green and black mussels have the same fundamental features as a delectable bivalve mollusc, but they vary in appearance, regionality, flavor, and culinary applications.

Green Mussels vs. Black Mussels: How Do They Look?

Green and black mussels have similar overall shapes, with an oblong and asymmetrical teardrop-like shape.

The color difference between these two species of mussels is the most noticeable. A green lipped mussel will be grayish-brown in color with a stunning emerald green tint around the edge. A black mussel’s shell, on the other hand, will be more consistent, ranging from deep brown to stunning midnight black.

Moreover, green mussels may grow significantly bigger than black mussels, up to double the size! Black mussels grow to be around 3 inches long, whereas green lipped mussels may grow to be 6 inches long.

Green Mussels vs. Black Mussels: Where Are They From?

Green mussels are indigenous to the Indo-Pacific area, and although they are most often associated with New Zealand, they have expanded and may now be found throughout the shores of both North and South America. Green lipped mussels are classified an invasive species in the Gulf of Mexico because they have started to harm the local environment and aquaculture.

Since black mussels may be any of many mussel species, they can be found all over the globe. Black mussels may be found in the cold seas off North America’s Pacific and Atlantic coastlines, as well as in South Africa and parts of South America.

Green Mussels vs. Black Mussels: How Do They Taste?

Many people are probably acquainted with the flavor of black mussels, but you may be wondering what green mussels taste like. Both black and green mussels have a somewhat sweet taste in their flesh, but black mussels have a stronger, saline flavor, and green mussels have a softer flavor that is more savory than sweet.

Black mussels have a more plump texture with a tender and squishy feel, while cooked green mussels have a firmer, chewier texture.

Green Mussels vs. Black Mussels: How Are They Used?

Except from where their variations in size might have an effect on the meal, black and green mussels may be utilized interchangeably. Although there are some taste changes, if a recipe asks for green mussels and you can only get black mussels, the substitute will work just fine.

Because of their small size, black mussels are ideal for meals like mussels escabeche or mussels with linguine. Green mussels, on the other hand, have a greater size that makes them ideal for stuffing and broiling, or grilling on the half shell.

Other Types of Mussels

Green mussels and black mussels aren’t the only mussels present! There are a few different varieties of mussels that are often mentioned.

Zebra Mussels

Zebra mussels live in freshwater and have a distinctive striped pattern on their shells, which gave them their name. Zebra mussels are relatively little, reaching only around 1 inch in length, and are considered an invasive species due to the way they dominate the habitats in which they live. Zebra mussels are theoretically edible, just like regular mussels, but their small size means they lack substance and aren’t very tasty.

Blue Mussels

Blue mussels, like their green counterparts, are sometimes known as blue lipped mussels. These mussels are found all over the globe and are distinguished by their distinctive blue or bluish purple hue. Prince Edward Island (PEI) mussels are another common name for blue mussels.

Mediterranean Mussels

Mediterranean mussels are a subspecies of blue mussels known as Mytilus galloprovincialis. These mussels may grow up to 5 inches long and have a distinctive large mouth and thin base. Mediterranean mussels, as opposed to black mussels, thrive in warmer seas.

Tips for Cooking With Mussels

There are several methods to prepare mussels, whether green or black. There are several wonderful mussel recipes available, but here are the essential techniques and tricks:

  • Examine the mussels well before cooking them. With no fractures or chips, the shells should be generally clean and lustrous. The mussel shells may be slightly open, but when tapped against another, they should clasp together. If it does not shut, the mussel is dead and should not be eaten.
  • While preparing mussels, you may see a little tangle of string-like fibers hanging off one side. Take hold of these strands and pull hard to remove them. This is known as the mussel’s beard, and it is used by the mussel to attach itself to rocks and other mussels. That’s quite awesome! But, it is not tasty.
  • Some people discovered that placing bivalves in a bowl of fresh water to enable them to purge themselves is the best method to remove the sand out of them. Most farmed mussels are cultivated on vertical ropes or pilings high up and away from the sand and muck, so this is no longer essential. As a result, the mussels arrive at the market perfectly clean, both inside and out!
  • Although raw shellfish like oysters and clams are ubiquitous, half shell mussels are a more uncommon appearance at the raw bar. This is owing to the danger presented by a form of bacterium known as Vibrio, which may get stuck in specific species of bivalves due to the way they filter water to eat. It is critical to be mindful of any known pollutants in the region while collecting fresh mussels.
  • Just steaming mussels is one of the most common ways to eat them. As you steam mussels, the shells open, releasing a deliciously saline, flavored juice into the cooking liquid. Mussels are often cooked in white wine and then seasoned with lemon juice, fresh herbs, and breadcrumbs.

  • The mussels should be quite clean overall, needing just a quick scrape or two. The shells must be bright, whole, and wet. If the shells seem dry and uninteresting on the surface, the mussel flesh inside will be the same.
  • Fresh mussels should smell clean and marine, not fishy or highly scented. Be warned that the liquid produced by mussels while cooking may be a little salty, and you may notice a whiff of this natural brininess in their fragrance as well.
  • Every mussels are packed with a shellfish tag indicating the date and location of harvest. You may sometimes find this tag attached to a bag of mussels, or if you buy the mussels from a supermarket’s seafood area or a local fish market, you can always inquire for this information.
  • Several big grocery shops sell frozen green or frozen black mussels, however they are often partly (or entirely) cooked, which might result in a strange texture in some culinary applications. If you choose frozen mussels, do your homework and check the label to verify there are no needless additions or preservatives. When feasible, get frozen raw mussels for the best texture; just be sure you properly boil them!
