Understanding Scallops: What They Are and How to Select Them

Scallops are shellfish that live on the ocean floor. They're prized in kitchens around the world for their sweet, tender meat and delicate flavor. The edible part of a scallop is the large white muscle that opens and closes the shell. This muscle is what you'll prepare and cook. There are several types of scallops available in markets, and understanding the differences helps you choose the right ones for your cooking needs.

Sea scallops are the largest variety, typically ranging from one to two inches across. They come from deeper ocean waters and have a firmer texture than their smaller cousins. Bay scallops are smaller, usually about one-half inch across, and come from shallower waters near coastlines. They tend to be sweeter and more tender. Calico scallops are the smallest option and are often sold already shucked. When shopping, you'll find scallops either in their shells or already removed. Fresh scallops should smell like the ocean—briny and clean—not fishy or ammonia-like.

The way scallops are processed affects how they cook. Dry scallops have not been treated with preservatives and will brown better when seared. Wet scallops have been treated with sodium phosphate, which helps them retain moisture but prevents proper browning and can create a rubbery texture. Look for labels indicating dry scallops when possible. Color matters too: fresh scallops range from translucent white to pale pink or orange, depending on the species. Avoid any that appear overly white or have a strong chemical smell, as these signs suggest heavy processing or age.

When selecting scallops at the market, choose ones that feel firm to the touch. If buying from a seafood counter, ask the fishmonger when they received their shipment. Scallops are best used within one or two days of purchase. Store them in the coldest part of your refrigerator, preferably on ice in a bowl that allows drainage. Cover them loosely so they can breathe. If you cannot use them within two days, freezing is a reasonable option, though fresh scallops have superior texture and flavor.

Takeaway: Seek out dry sea or bay scallops that are firm, smell fresh and briny, and come from a reputable fishmonger. Plan to cook them within one to two days for the best results.

Cleaning and Preparing Scallops for Cooking

Proper preparation is essential before cooking scallops. Even though scallops are relatively simple to work with, a few steps ensure the best texture and flavor in your finished dish. The first task is removing the side muscle, sometimes called the foot. This small, tough piece of tissue clings to the side of the white muscle and must be removed. Look for a small, rectangular piece of tissue about the size of a grain of rice positioned on the side of the scallop. You can pull it away with your fingers or use a paring knife to cut it away. This muscle will not cook tender like the rest of the scallop, so do not skip this step.

If your scallops still have their shells, you'll need to shuck them first. Place a scallop on a cutting board with the flat shell on top and the curved shell on the bottom. Insert a thin, sharp knife under the flat shell and slide it across to cut the muscle holding the shells together. Lift off the flat shell and repeat on the curved shell underneath. Once both shells are removed, you'll see the scallop meat. Rinse it under cool running water to remove any sand or shell fragments. Pat the meat dry with paper towels. This drying step is crucial for proper cooking—moisture on the surface prevents browning.

After removing the side muscle and patting the scallops dry, check each one for sand. Sometimes grit becomes lodged in the crevices. Run your fingers gently across the surface to feel for sand. You can also rinse again if needed, but make sure to pat them completely dry once more. Some cooks prefer to pat scallops dry, then refrigerate them uncovered for 15 to 30 minutes before cooking. This helps remove surface moisture that would otherwise inhibit browning in the pan.

Consider the size of your scallops when planning your cooking method. Large sea scallops work best for searing because they're thick enough to develop a golden crust without overcooking inside. Small bay scallops cook too quickly when seared and are often better suited to poaching, steaming, or adding to pasta dishes at the last moment. Never skip the drying step regardless of cooking method—this affects texture and browning dramatically.

Takeaway: Remove the side muscle, shuck if needed, rinse to remove sand, and pat completely dry with paper towels before cooking. Let scallops rest uncovered in the refrigerator for 15 to 30 minutes if possible to ensure maximum dryness.

Searing Scallops: The Pan Method for Perfect Results

Searing is the most popular cooking method for preparing scallops at home, and it yields restaurant-quality results when done correctly. This technique creates a golden, caramelized crust while keeping the inside tender and slightly translucent. To sear scallops, you'll need a heavy-bottomed pan—cast iron or stainless steel works best because these materials distribute heat evenly and can withstand high temperatures. Non-stick cookware is not ideal because scallops require very high heat that can damage non-stick coatings.

Start by heating your pan over medium-high heat for two to three minutes. You want the pan hot enough that a drop of water sizzles immediately on contact. While the pan heats, season your scallops with salt and black pepper on both sides. Add a small amount of oil with a high smoke point to the hot pan—vegetable oil, canola oil, or clarified butter all work well. Avoid olive oil for searing because it has a lower smoke point and will burn at the required temperature. Let the oil heat until it shimmers and just begins to smoke.

Place the scallops gently into the hot oil, flat-side down. They should sizzle immediately. Resist the urge to move them. Leave them undisturbed for two to three minutes while the first side develops a golden-brown crust. This patience is the key to proper searing. Once the crust forms, flip each scallop carefully and cook the other side for another one to two minutes. The entire cooking process typically takes three to five minutes depending on scallop size. Large sea scallops take longer than small bay scallops.

You can test for doneness by touch. A properly cooked scallop should feel slightly firm but still have a bit of give when pressed gently with your finger. Overcooked scallops become rubbery and tough, so timing is important. If you're uncertain, it's better to remove scallops slightly undercooked than to cook them too long. They will continue cooking slightly as they rest. Remove them from the pan and let them rest for one to two minutes before serving. You can add butter, garlic, and fresh lemon juice to the pan to create a simple sauce for serving.

Takeaway: Heat your pan until it's very hot, use high-smoke-point oil, sear scallops without moving them for two to three minutes per side, and serve immediately. Season simply with salt, pepper, and lemon for the best flavor.

Poaching and Steaming Methods for Gentle Cooking

While searing creates a crust, poaching and steaming are gentler cooking methods that preserve moisture and work well for smaller bay scallops or when you want a more delicate dish. These methods are also useful if you're preparing scallops for a cream sauce, pasta dish, or salad where you don't want a strong crust. Poaching involves simmering scallops in liquid, while steaming cooks them above simmering liquid using steam. Both methods preserve the natural sweetness of scallops.

To poach scallops, bring a shallow pot of liquid to a gentle simmer. Use fish stock, chicken stock, or even water with white wine and a pinch of salt. The liquid should be flavorful but not overpowering. Keep the heat at a bare simmer—you should see only occasional bubbles rising to the surface. Place prepared scallops into the simmering liquid. They will start to
