Here, find out the differences between these types of scallops.

They are small in size with a diameter of about 1/2 inch.

Bay scallops have a sweet flavor and tender meat.

Use bay scallops in pasta dishes, salads, paellas and more.

Sea scallops, like the name suggests, come from cold sea waters.

Sea scallops are found in deeper waters than bay scallops, and they’re harvested year-round.

They are larger in diameter, usually 1 1/2 to 2 inches.

While still sweet and tender, sea scallops can be chewier than bay scallops and aren’t as sweet.

Sea scallops are more expensive than bay scallops.

Fresh vs.

So the “fresh” seafood you’re buying might not be at its peak freshness.

Wet-packed scallops are often treated with sodium triphosphate, a preservative that is designed to extend the shelf life.

However, the preservative adds to the scallops' water weight.

Scallops are often priced per pound, so buying wet-packed scallops means you end up paying more for water.

On the other hand, dry-packed scallops don’t feature artificial preservatives.

Instead, they retain their natural moisture content.

Without the excess water, dry-packed scallops also have a silkier texture and are easier to sear.

When possible, choose dry-packed scallops.

These scallops are immediately sold, so they are at peak freshness.

Both diver and dayboat scallops can be on the pricier side due to their more intricate processes.

Scallops farmed using a bottom culture method are ranked the best choice,according to Seafood Watch.

If you’re looking to buy bay scallops,the organization recommendsbuying them from Massachusetts or New York.

If you’re looking to buy sea scallops,Seafood Watch suggestspurchasing farmed scallops from Alaska.

The Bottom Line

Bay scallops and sea scallops are the two most common types of scallops.

Bay scallops are more affordable than sea scallops, which are larger in size.

When buying scallops, look for ones that are dry-packed.

Whichever scallop you choose, you’re sure to have a sweet, tender protein source.
