Do scallops and shrimp cook at the same rate?

Scallops and shrimp do not cook at the same rate. Scallops are a type of shellfish that is typically much thicker than shrimp and therefore they take longer to cook. Shrimp are a type of crustacean that is typically much thinner than scallops and therefore they cook much faster. To ensure that both scallops and shrimp are cooked properly, it is recommended to cook them separately. Shrimp will typically only take a few minutes to cook while scallops can take several minutes or even up to an hour depending on the size.
