Understanding Scallop Sizing: The Count-per-Pound System
Determining the correct portion of sea scallops begins with understanding their classification system. Scallops are not sold by a uniform size, but rather by a 'count per pound.' This number, often seen on packaging, tells you how many individual scallops you can expect in one pound of product. For example, a label of '10/20' means there are between 10 and 20 scallops per pound. Conversely, the largest scallops are marked with a 'U' for 'under'—as in U/10, meaning there are fewer than 10 scallops in a pound. This system is critical because the size directly influences how many scallops are needed to form a single serving.
Interpreting Size Labels
To make an informed decision, you should look for one of these common labels and understand what it implies about the scallop size and, by extension, the portion size:
- U/10: These are super colossal scallops, the largest size available. A small number of these can quickly create a substantial portion.
- 10/20: Known as colossal or jumbo scallops, these are excellent for searing and will require more scallops per serving than U/10s.
- 20/30: This is a versatile medium-large size, well-suited for various cooking methods.
- 30/40: Considered a large scallop, this is a good choice for dishes where scallops might be a secondary component, or for when you want to serve more pieces per person.
- 40/60: These medium-sized scallops are ideal for mixing into pastas or stir-fries.
The Ideal Serving Size for Appetizers and Entrées
The purpose of the dish plays a major role in how many scallops you should serve. A light appetizer calls for a much smaller portion than a hearty main course.
Appetizer Portions
For an appetizer or starter, a serving of 3 to 4 ounces of scallops per person is generally recommended. This lighter portion allows guests to enjoy the sweet, rich flavor without feeling too full before the main meal. For larger scallops, this may mean just 2 to 4 pieces per plate, while smaller ones could be more.
Entrée Portions
As a main course, scallops take center stage and require a more substantial portion. An entrée serving size typically ranges from 6 to 8 ounces per person. This provides a satisfying amount of protein and is the perfect foundation for pairing with other sides like risotto, vegetables, or pasta. For larger scallops, this could be 4 to 6 pieces, whereas smaller ones might require up to 11 or more.
Scallop Serving Size Comparison Table
Understanding the count-per-pound system makes it simple to visualize how many scallops you will need for your meal. Here is a handy comparison to help you plan:
| Scallop Size (Count/lb) | Typical Number of Scallops per 3 oz Serving | Recommended Use Case |
|---|---|---|
| Super Colossal (U/10) | 2–4 scallops | Searing, grilling, or high-end entrées |
| Colossal/Jumbo (10/20) | 2–4 scallops (colossal); 4-6 scallops (jumbo) | Searing, grilling, entrées |
| Medium-Large (20/30) | 4–6 scallops | Versatile for pan-searing, baking, or broiling |
| Large (30/40) | 6–8 scallops | Sautéing, pasta dishes, stir-fries |
| Medium (40/60) | 8–11 scallops | Soups, stews, seafood salads |
| Small (60/120) & Petite (120+) | 11–23 scallops (small); 23–35 scallops (petite) | Ceviche, sauces, pastas, casseroles |
How Cooking Method Affects Scallop Serving Size
It's important to remember that scallops, like all seafood, will shrink slightly during the cooking process. This is due to water weight loss and can be more or less pronounced depending on the type of scallops you purchase. The cooking method itself also impacts the final size and texture.
Wet vs. Dry Scallops and Water Weight
When buying scallops, you will often find two options: wet or dry. Dry scallops are untreated and retain their natural flavor and texture. Wet scallops, however, are treated with a preservative solution (STP), which causes them to retain excess moisture. While this makes them appear larger and whiter, this water weight is released during cooking, causing significant shrinkage and making it harder to achieve a proper sear. This is why many chefs and home cooks prefer dry scallops, as their predictable size and superior searing quality result in a better dish.
Nutritional Information for a Standard Serving
Beyond size and preparation, it's also helpful to consider the nutritional content of a standard scallop serving. A 100-gram serving (approximately 3.5 ounces) of scallops is a lean, protein-rich option, providing around 24 grams of protein and about 137 calories, before any added oils or butter. They are also a great source of minerals like magnesium and potassium and contain beneficial omega-3 fatty acids. Keeping this in mind can help you balance your overall meal, whether it's a lean and light appetizer or a complete protein-packed entrée.
Conclusion: Making the Right Choice
So, what is a serving size of sea scallops? It's not a single answer, but a consideration of several factors. By understanding the count-per-pound system, differentiating between appetizers and entrées, and recognizing the impact of buying wet versus dry scallops, you can ensure a perfect, well-proportioned meal every time. Remember to choose your scallop size based on your desired dish and plan your portions accordingly. This knowledge empowers you to confidently cook and enjoy one of the ocean's most delectable delights.
