SUSHI EBI 4L - These shrimp are specifically prepared for sushi applications. They are typically peeled, deveined, cooked (blanched), butterflied (split open from the belly and flattened), and skewered to keep them straight during cooking with the tail portion left intact for presentation. They are a ready-to-use product after thawing.
4L: This is the size grade in a specific commercial system for sushi ebi. "4L" indicates that the shrimp are large, typically measuring approximately 9.1 cm to 9.5 cm (about 3.6 to 3.7 inches) in length. In general, the more "L"s in the grading (e.g., 5L, 6L), the larger the shrimp.
