What Are Black Mussels
Black mussels are perhaps the most widely-known and consumed mussel species. They are among the two species found throughout the U.S., the other being the green mussel.
They are often mistaken for blue mussels due to their resemblance, but they’re distinct.
Blue mussels have a blueish color, whereas black mussels are black. Their shapes and sizes closely resemble one the other, and to distinguish them; you must look at the color of their shells.
Black mussels are abundant on the Pacific and Atlantic coasts, where cooler temperatures. Some of the countries that have the most aquaculture-intensive mussels are South Africa, Canada, China, and the United States.
Farming
The mussels are cultivated in the wild, typically grown naturally to be harvested. Ropes are suspended from tightly packed areas to ensure that mussels can develop on them.
Another reason is that black mussels are more frequent than green mussels. If they grow naturally and require little effort, they can produce more significant amounts.
Specifications of Black Mussels
Black mussels are the most commonly used; therefore, you already know their appearance. Their size averages approximately 2.5-inches long, but it can depend on where you purchase them from.
Black mussels are incredibly intense in their taste that is not matched with other varieties. They also have a tender and soft texture, chewier than green mussels.
Cost and Availability
Black mussels are found all over the world. This is partly due to the way they are kept and their natural habitat.
They can be found freshly frozen or in a variety of varieties. They can be as a whole, half-shelled, or even as a single piece of mussel (meaning there is no shell). It is also possible to see that they can be flavored or marinated.
The common mussels are the species that produce pickled or canned mussels.
Because it’s available all year long, the price is extremely reasonable and in some places even shockingly low!
What Are Green Mussels
As mentioned previously, green mussels are another popular species found within the U.S. and most other countries. Also, you will notice that they can be referred to by the name “Green Lipped Mussels.”
The mussels are native to New Zealand and regions in the Pacific Rim (the Western shores in North and South America). However, several countries, such as India, have begun cultivating these mussels in open water.
Farming
Since these mussels originate from New Zealand, many countries raise them independently. The regulations and restrictions are incredibly stringent and carefully observed. Farmers’ mussels need high-quality water and food.
Specifications of Green Mussels
The beautiful mollusk is the typical shape of mussels, but they’re much more prominent in dimensions, almost twice as larger than your standard white mussel. They’re about 6 inches in length, which naturally impacts the price.
The mussels are very hard-soft, chewy, and tender texture. It is evident that the flavor isn’t as strong compared to other species; however, they are still delicious, and some say they are slightly sweet.
Cost and Availability
Since these mussels are nearly only grown naturally within New Zealand or otherwise farmed, their price is considerably higher. They aren’t many, but they’re tricky to locate as black or blue mussels.
The bigger size means they are more expensive and their seasonality.
While challenging to find, these green mussels are also available either frozen or fresh and come in various forms, such as half shell, whole, and even with meat only.
What to Look For When Buying Mussels
When buying muscles, they should be bought fresh and still alive – a closed shell means it’s fresh and alive. Mussels are similar to many other shellfish, they spoil fast, so you should prepare and eat mussels on the day you purchase them, or you run the risk of food poisoning. This is very easy with mussels as they spoil quickly.
In order to store mussels correctly, put them into a bowl and place them into the refrigerator covered with a damp towel. Don’t store them in a bowl of water, especially tap water, as this will kill them very quickly and it will stink your refrigerator.
What’s The Difference Between Them?
Having reviewed the various seafood products separately, let’s examine their characteristics.
Most importantly, the color of their fur is what differentiated the two species the most.
Green-lipped mussels sport an evident grey shell adorned with gorgeous green hues. A deep and dark blue shell characterizes the black mussels.
Another characteristic that sets them apart from one another is their dimensions. Green mussels tend to be larger than the standard black mussel. However, they can both differ in size.
Black mussels are known for their soft and tender texture, and green mussels are known for their slightly chewier texture.
In terms of their taste, like every ingredient, it all comes down to individual taste, and neither one is “better” compared to the other. Black mussels possess a vibrant and sweet taste, and green mussels don’t have as much of a presence.

The method in which mussels are raised also differs significantly. Mussels of black are cultivated in their natural habitat by ropes, making them quick and simple to catch.
They are also located in many regions around the globe where they are abundant.
Green mussels are, however, extremely rare, despite being quite common. Their rarity is that they are only naturally occurring in New Zealand and some coasts in South and North America.
The raised green-lipped mussels are farmed and are therefore more expensive to make, hence the higher cost.
Considering they’re pretty popular, both of these varieties are available either in fresh or frozen form. In regions where they aren’t growing or being raised in any way or other, you’ll discover that frozen varieties are easier to locate.
In the local regions where they are plentiful, You will notice that you can quickly locate both frozen and fresh versions, of which the fresh varieties are just a little more costly.
In the next step, you’ll discover the entire mussels and half-shells and the meat of the mussel in frozen and fresh versions. Also, you can find them in canned or pickled forms and in a range of refreshing and tasty flavor combinations.
Cooking Green and Black Mussels
When we examine the way each one can be used and how they’re used, they’re in a way interchangeable. Their tastes and textures are similar enough that it is possible to pick either due to the availability, price, and aesthetic appearance.
People consume mussels for two reasons: diet and health or simply because it’s delicious.
Mussels offer numerous health benefits and are a great choice as part of a pescatarian diet. They’re high in nutritious and healthy proteins and omega-3 fatty acids, and many vitamins and minerals.

Green-lipped and black mussels are great with the same components for flavor. The most flavorful accompaniments to seafood are always fresher and more flavorful, like lemon juice, zest, fresh olive oil, fresh herbs, and even pickled items.
Garlic and wine are an effective and classic combination of flavors that wonderfully improve mussels’ natural taste.
The most creative ideas for mussels recipes are steam garlic, fennel, and wine mussels. There are also deep-fried, herb-crusted meats of mussels or some baked, cheesy mussels.
Steaming Green and Black Mussels
If you are cooking mussels, it is possible to use any available mussels. Most often, the whole and half shell mussels are cooked. However, the meat of mussels can be steamed to preserve the nutrients.
Both species of mussels are cooked in the same way. However, their cooking times will differ. Since green mussels are naturally larger, they need to cook longer than black mussels.
Black mussels can cook for around 7 minutes, and green mussels need to cook for between 10 and 12 minutes.
Steaming mussels is an excellent cooking technique that can help its meat retain its flavor, moisture, and nutrients and enhance the mussels’ color.
Steaming is also a great way to blend flavors of other ingredients, such as wine and garlic, herbs, and onion. You can find a variety of flavor options to play with.
How to Steam Mussels
- Sauté any vegetable or spices, aromatics, herbs, or vegetables you’d like to add.
- Then, add the mussels into the pot and immediately add the water base. It could be stock, broth wine, wine, or simply water.
- Cover the pan or pot with the lid and let the black mussels cook for around five minutes and the green mussels for about 10-minutes.
- Take off the lid and examine if most lids have opened, indicating that they’re fully cooked. If they’re still not ready, place the top on the pot and cook for two or three minutes.
- Serve it warm and preferably with cooking liquid. Garnish with fresh herb and zest.
Pan-Fried Green Mussels and Black Mussels
Another excellent and widespread method to cook mussels is to pan-fry the mussel’s meat. This allows them to let the flavors of the meat out and gives them a smokey note.
The most simple mussels to cook in a pan are ones that do not have shells. However, there are recipes for sautéing whole mussels added to a base sauce to further cook after opening.
The shells themselves have beautiful flavors that can be added to dishes.
Pan-frying mussels must be cooked using an ingredient that is liquid or wet. This is to stop the mussels from drying out and sticking to the pan or overcooking. Nothing is more unpleasant than a rubbery, chewy mussel!
How to Pan-Fry Mussels
- Saute the main ingredients such as garlic, vegetables, and herbs. Add spices, herbs, and other ingredients of your choice.
- Add a tablespoon of oil before adding all the mussels, and then toss them around for approximately two minutes. They should begin to pop open.
- Include your base liquid-like wine or broth, and cook them for a while until they’re fully released.
- Serve them immediately when they’re still hot and freshly cooked. You can garnish them with flavors that complement them, such as lemon or Dill.
