Scallops are one of the most sought-after seafood delicacies globally, prized for their tender flesh, sweet flavor, and versatility in various culinary dishes. Whether you’re a seafood enthusiast, a chef, or a curious foodie, understanding what scallops are and what makes them so special is essential. In this article, we’ll embark on a journey to explore the fascinating world of scallops, covering their biology, types, nutritional benefits, cooking methods, and more.
What are Scallops?
Scallops are a type of marine bivalve mollusk, belonging to the family Pectinidae. They are closely related to clams, mussels, and oysters, but with some distinct characteristics that set them apart. Scallops are characterized by their fan-shaped shells, typically between 4-6 inches in length, with a smooth, shiny surface that ranges in color from pale pink to deep orange.
Scallops have a unique body structure, consisting of a soft, white adductor muscle that allows them to open and close their shells quickly. This remarkable ability to swim rapidly by clapping their shells together enables them to escape predators and navigate through the water. Scallops also have a large number of tiny, bead-like eyes along the edge of their mantle, which help them sense light and darkness.
Habitat and Distribution
Scallops are found in oceans worldwide, typically inhabiting shallow, coastal waters with soft or sandy bottoms. They thrive in areas with moderate water temperatures, usually between 40°F and 70°F (4°C and 21°C), and can be found at depths ranging from 10 to 100 feet (3 to 30 meters). Some species, like the Atlantic sea scallop, prefer to dwell in estuaries and bays, while others, such as the Japanese scallop, inhabit deeper waters.
Types of Scallops
While there are over 400 species of scallops, only a few are commercially harvested and widely available in markets. Here are some of the most popular types:
Atlantic Sea Scallop (Placopecten magellanicus)
Native to the North Atlantic Ocean, this species is one of the most prized and widely consumed. Atlantic sea scallops are known for their sweet, tender flesh and are often harvested in the wild off the coasts of the United States and Canada.
Pacific Sea Scallop (Patinopecten yessoensis)
Found in the coastal waters of Japan and Eastern Asia, Pacific sea scallops are smaller than their Atlantic counterparts but share a similar flavor profile. They are often farmed in Japan and other Asian countries.

What is the flavor profile of scallops?
Scallops have a delicate flavor profile that is often described as sweet and tender. The flavor is often compared to that of a cross between a shrimp and a mussel, but with a more refined taste. The scallop’s flavor profile is also influenced by the type of water it comes from, with scallops from colder waters having a slightly sweeter taste than those from warmer waters.
When cooked, scallops can take on a variety of flavors depending on the seasonings and ingredients used. They pair well with a range of flavors, from the brightness of lemon and herbs to the richness of cream and butter. Whether grilled, pan-seared, or baked, scallops are a versatile ingredient that can be prepared in a multitude of ways to bring out their natural sweetness and tender texture.
Are scallops a sustainable seafood choice?
Scallops are considered a sustainable seafood choice when harvested responsibly. Scallops are a low-impact fishery, meaning they do not require large amounts of fuel or gear to catch. Additionally, scallop fisheries often have a low bycatch rate, which means they do not unintentionally catch non-target species. Many scallop fisheries around the world are also certified by organizations such as the Marine Stewardship Council (MSC), which ensures that they meet rigorous sustainability standards.
However, it’s essential to note that not all scallop fisheries are created equal. Some scallop fisheries may have higher environmental impacts due to habitat damage or bycatch. When purchasing scallops, look for certifications from organizations like the MSC or ask your fishmonger about the source of the scallops to ensure you’re making a sustainable choice.
How do I store scallops?
Scallops are a perishable product and require proper storage to maintain their quality and safety. When storing scallops, it’s essential to keep them cold and dry. Fresh scallops should be stored in a covered container in the refrigerator at a temperature below 40°F (4°C). They should be consumed within a day or two of purchase, or frozen immediately to preserve their quality.
If you need to store scallops for a longer period, freezing is the best option. Scallops can be frozen whole, shucked, or as scallop meat. When freezing scallops, it’s crucial to wrap them tightly in plastic wrap or aluminum foil to prevent freezer burn. Frozen scallops can be stored for up to 12 months. Always label the package with the date and contents, so you can easily keep track of how long they’ve been stored.
Can I eat scallops raw?
Yes, scallops can be eaten raw, but it’s essential to handle them safely to avoid foodborne illnesses. Raw scallops are often served as sashimi or ceviche, and they require proper handling and storage to ensure their safety. When consuming raw scallops, make sure they are fresh, have been stored at a safe temperature, and have been handled hygienically.
Only consume raw scallops from a trusted source, and make sure they have been labeled as “sashimi-grade” or “suitable for raw consumption.” Additionally, always follow proper food safety guidelines when handling and preparing raw scallops, such as washing your hands thoroughly, using clean utensils, and refrigerating them promptly.
Are scallops high in mercury?
Scallops are considered a low-mercury seafood option. Mercury is a toxic substance that can be found in small amounts in fish and shellfish. While scallops do contain some mercury, the levels are typically very low. According to the United States Environmental Protection Agency (EPA), scallops have a mercury level of around 0.025 parts per million (ppm), which is significantly lower than many other types of fish and shellfish.
As a result, scallops are considered a safe choice for most people, including pregnant women and young children. However, it’s always a good idea to vary your seafood choices and consume a range of options to minimize exposure to mercury and other contaminants.
Can I cook scallops in a microwave?
While it’s technically possible to cook scallops in a microwave, it’s not the recommended cooking method. Microwaves can cook scallops unevenly, leading to overcooked or undercooked areas. This can result in a tough, rubbery texture and a less appealing flavor.
Instead, try cooking scallops using more traditional methods, such as grilling, pan-searing, or baking. These methods allow for more control over the cooking temperature and time, resulting in a tender, flavorful dish. If you’re short on time, consider cooking scallops in a skillet on the stovetop or in the oven, as these methods are quick and easy.
Are scallops nutritious?
Scallops are an excellent source of protein and nutrients. They are low in calories and fat, but rich in vitamins, minerals, and omega-3 fatty acids. A 3-ounce serving of scallops provides around 18 grams of protein, as well as essential nutrients like vitamin B12, selenium, and phosphorus.
Scallops are also a good source of antioxidants and have been linked to several potential health benefits, including improved heart health, reduced inflammation, and enhanced cognitive function. Additionally, scallops contain a range of minerals, including magnesium, potassium, and iron, making them a nutritious addition to a balanced diet.
