Scallops, with their delicate sweetness and tender texture, are a culinary delight enjoyed worldwide. From elegant restaurants to home kitchens, these bivalve molluscs offer a versatile and flavourful protein source. This comprehensive guide explores everything you need to know about scallops, from their origins and preparation to cooking techniques and nutritional value.
Scallops: A Culinary Journey from Ocean to Plate
1. History of Scallops
Scallops have been a part of human diets for centuries, with archaeological evidence suggesting their consumption dating back to prehistoric times. They are found in oceans worldwide, and the specific type of scallop varies by region. The most commonly consumed scallop in many Western cuisines is the sea scallop ( Placopecten magellanicus), found in the North Atlantic. Throughout history, coastal communities have relied on scallops as a source of food, and they have held cultural significance in various regions. They were historically harvested by hand, and later with dredges.
2. Cooking Techniques
How to Cook Scallops (General Overview)
Scallops are best cooked quickly over high heat to achieve a beautiful sear on the outside and a tender, slightly translucent interior. Overcooked scallops become tough and rubbery. The key is to pat them dry before cooking to achieve a good sear. Season simply, allowing the natural sweetness of the scallop to shine. Don't overcrowd the pan.
How to Prepare Scallops for Cooking
- Thaw: If frozen, thaw scallops completely in the refrigerator overnight. Fresh scallops are best, but if using frozen, ensure they are fully defrosted and drained of excess water.
- Rinse and Pat Dry: Rinse the scallops under cold running water and pat them very, very dry with paper towels. This step is crucial for a good sear.
- Remove the 'Foot' (Optional): Some scallops may have a small, tough muscle called the 'foot' attached. You can remove this with your fingers or a small knife, but it is edible.
How to Grill Scallops
- Prepare the Grill: Preheat the grill to high heat.
- Oil the Grate: Lightly oil the grill grates to prevent sticking.
- Season the Scallops: Pat the scallops dry and season with salt, pepper, and, optionally, a little olive oil.
- Grill: Place the scallops directly on the hot grill grates. Grill for 2-3 minutes per side, or until they develop a nice sear and are cooked through.
- Serve: Remove from the grill and serve immediately.
How to Bake Scallops
- Preheat the Oven: Preheat the oven to 200°C (180°C fan/ Gas Mark 6).
- Prepare the Scallops: Prepare the scallops as described above.
- Arrange: Place the scallops in a baking dish, lightly oiled or lined with parchment paper.
- Season and Top (optional): Season the scallops with salt, pepper, and your desired flavours (e.g., garlic butter, herbs). You can also add toppings like breadcrumbs or grated cheese.
- Bake: Bake for 8-12 minutes, or until the scallops are cooked through and slightly golden.
How to Sauté Scallops
- Heat the Pan: Heat a heavy-bottomed skillet (cast iron is ideal) over medium-high heat.
- Add Oil: Add a high-smoke-point oil, such as olive oil, avocado oil, or clarified butter. The pan should be shimmering.
- Sear the Scallops: Place the scallops in the hot pan, ensuring they are not overcrowded. Sear for 2-3 minutes per side, or until golden brown and cooked through.
- Season: Season with salt, pepper, and any other desired spices or herbs during the searing process or just after.
- Finish (Optional): You can add a knob of butter, a splash of white wine, or lemon juice to the pan at the end to create a quick pan sauce.
- Serve: Serve immediately.
3. Ingredient Preparation
While scallops come in various sizes, the core preparation remains consistent.
How to Cut Scallops
Scallops do not need to be cut unless you're creating smaller pieces for ceviche or tartare. In such cases, gently slice the scallops into the desired size using a sharp knife, taking care not to crush them.
How to Peel Scallops
Scallops don't need to be peeled. The edible part is the muscle itself, which is the white, fleshy part.
How to Dice Scallops
As mentioned above, dice scallops for dishes like ceviche or tartare. Use a sharp knife and gently cut the scallop into uniform cubes.
How to Mince Scallops
Scallops aren't typically minced. If you want to incorporate them into a pate or filling, you can finely chop them after they have been cooked.
4. Storage
How to Store Scallops
- Fresh Scallops: Store fresh scallops in the coldest part of your refrigerator (usually the bottom shelf) in a shallow dish, covered with a damp paper towel or a slightly damp cloth. Do not seal them airtight. Never store them submerged in water. This helps prevent them from drying out while allowing air circulation. They should ideally be used within 1-2 days of purchase.
- Frozen Scallops: If the scallops were previously frozen, ensure they're properly thawed in the fridge before cooking. Do not refreeze thawed scallops. If you buy scallops frozen, you can store them in the freezer for up to 3 months, well-sealed to prevent freezer burn.
How Long Do Scallops Typically Last Under Different Storage Conditions?
- Fresh: 1-2 days in the refrigerator.
- Frozen (raw): Up to 3 months in the freezer.
- Cooked: 3-4 days in the refrigerator, stored in an airtight container.
5. Substitutions
What are Good Substitutes for Scallops?
- For Flavor & Texture: Firm white fish like cod, monkfish, or halibut can provide a similar texture but won't have the same subtle sweetness. Imitation scallops, made from fish or other seafood, can be a substitute, but quality varies.
- For Dietary Considerations: Portobello mushrooms, pan-seared with a similar seasoning can act as a vegetarian alternative.
- For Allergies: Other shellfish, if not allergic, like shrimp or prawns, can be a substitution, but the flavor is very different.

Facts You May Not Know
- Scallops are bivalve molluscs, meaning they have two shells.
- They are capable of swimming by clapping their shells together.
- The white, fleshy part of the scallop is the adductor muscle, used to open and close the shells.
- Scallops are a good source of protein, vitamin B12, and selenium.
- The 'roe' (the orange part) is edible and considered a delicacy in some regions; however, often it's removed from the scallop before it is sold.
FAQs
Sustainability depends on the fishing practices. Look for scallops certified by organisations like the Marine Stewardship Council (MSC) to ensure they are sourced from sustainable fisheries.
What's the difference between 'dry-packed' and 'wet-packed' scallops?Dry-packed scallops are harvested without preservatives, and wet-packed scallops are soaked in a solution of sodium tripolyphosphate (STPP) which helps them retain water. Dry-packed are generally preferred, as they sear better and have a more natural flavour.
Can I eat the roe on scallops?Yes, scallop roe is edible and considered a delicacy in some cultures. However, it's often removed before the scallops are sold.
What wines pair well with scallops?Dry white wines like Sauvignon Blanc, Pinot Grigio, or a crisp Chardonnay pair well with scallops. Champagne or sparkling wine is also a great choice.
Can I freeze cooked scallops?Yes, you can freeze cooked scallops. Allow them to cool completely, then place them in an airtight container or freezer bag. They can last for up to 2-3 months in the freezer.
