Decoding Scallop Sizing for a Perfect Portion
Determining exactly how many sea scallops is 4oz requires a basic understanding of how scallops are sold and categorized. Scallops are not sold by a standard count per portion but rather by a count-per-pound label. This means that the number of individual scallops you receive for a given weight depends on their average size.
Size Matters: From Jumbo to Medium
Scallops are commercially graded by a range of numbers, indicating how many shucked scallops make up one pound. The lower the number range, the larger the individual scallops. This system is key to estimating your 4oz portion.
- Jumbo (U/10): Fewer than 10 scallops per pound. A 4oz serving would be approximately 2-3 scallops.
- Large (10/20): 10 to 20 scallops per pound. A 4oz serving would be approximately 3-5 scallops.
- Medium (20/30): 20 to 30 scallops per pound. A 4oz serving would be approximately 5-8 scallops.
The Calculation Explained
To find the number of scallops in 4oz, you can use a simple calculation based on the count-per-pound label. A pound is 16 ounces, so 4 ounces is one-quarter of a pound. Take the average of the count-per-pound range and divide it by four. For example, for large (10/20) scallops:
- Average count: (10 + 20) / 2 = 15 scallops per pound.
- 4oz portion: 15 / 4 = 3.75 scallops. So, around 3 to 4 large scallops.
The "Wet" vs. "Dry" Scallop Factor
Another critical detail that affects the weight and count of scallops is whether they are "wet" or "dry" packed. Dry scallops are natural and untreated, holding less water. Wet scallops, on the other hand, are treated with a sodium phosphate solution that makes them whiter and heavier by causing them to absorb more water. This added water weight is released during cooking, causing the scallops to shrink considerably and making it difficult to achieve a proper sear. For this reason, many chefs and food experts prefer dry scallops, despite their slightly higher cost per pound. If you are buying wet scallops, you may need more than 4oz to account for the water loss during cooking.
A Comparison of Scallop Sizing
| Scallop Size | Count Per Pound | Estimated Number in 4oz | Ideal for... |
|---|---|---|---|
| Jumbo (U/10) | Under 10 | 2-3 | Pan-searing, grilling |
| Large (10/20) | 10-20 | 3-5 | Pan-searing, grilling, pasta |
| Medium (20/30) | 20-30 | 5-8 | Sautéeing, stir-fries, appetizers |
| Bay Scallops | 60+ | 15+ | Soups, stews, casseroles |
Conclusion
Ultimately, the question of how many sea scallops is 4oz has no single answer, as it depends on the size classification of the scallops you purchase. By understanding the count-per-pound system, you can make an informed decision at the seafood counter. For a standard appetizer, you can expect anywhere from 3 large scallops to around 8 medium ones in a 4oz serving. Remember that opting for dry-packed scallops will ensure you get more scallop meat per ounce and a better cooking experience. Whether you're aiming for a few perfectly seared jumbo scallops or a generous portion of medium ones in a pasta dish, knowing the numbers will help you create a meal that is just right.

Recipe Idea: 4oz Pan-Seared Sea Scallops
For a simple, elegant meal, consider this recipe using 4oz of sea scallops. For a single serving, start with 3-5 large, dry-packed sea scallops. Pat them very dry with a paper towel to ensure a good sear. Heat a tablespoon of butter and a splash of olive oil in a pan over high heat until it smokes. Season the scallops with salt and pepper and place them in the hot pan, making sure they don't touch. Sear for about 1.5 to 2 minutes per side until a golden crust forms and the center is just opaque. Serve immediately with a squeeze of lemon and a sprinkle of fresh parsley.
Frequently Asked Questions
What does the U/10 or 10/20 on scallop packaging mean?
The number on scallop packaging indicates the count per pound. "U/10" means there are "under 10" scallops per pound, indicating a very large size. "10/20" means there are between 10 and 20 scallops per pound, indicating a large to medium size.
Are larger scallops more expensive per pound?
Yes, larger sea scallops, often hand-harvested by divers, tend to be more expensive per pound. This is due to the greater effort involved in harvesting and their rarity.
What is the difference between wet and dry scallops?
Dry scallops are untreated and hold less water, allowing for a better sear during cooking. Wet scallops are treated with a sodium phosphate solution that adds water weight, causing them to shrink more when cooked.
How many sea scallops are considered a typical entrée portion?
A typical entrée portion for sea scallops is usually around 6-8oz, which would equate to roughly 4-6 large scallops or 8-12 medium scallops, depending on their count-per-pound.
Why do scallops sometimes shrink when cooked?
Scallops shrink during cooking as they lose water. This effect is more pronounced in "wet" scallops, which are treated with a solution that causes them to absorb excess moisture.
Can I use bay scallops instead of sea scallops?
Yes, but with modifications. Bay scallops are much smaller and sweeter than sea scallops and require a much shorter cooking time to prevent them from becoming tough. They are better suited for dishes like stir-fries or gratins.
Is 4oz of sea scallops enough for a single serving?
Yes, 4oz is a standard appetizer portion for sea scallops. For a main course, you may want to increase the serving to 6-8oz.
