This is a premium canned seafood product featuring whole, cooked Chilean Blue Mussels (Mytilus chilensis). They are packed in a rich "Vieira" sauce, which is a scallop-flavored or scallop-based sauce. This mimics the luxurious flavor profile of scallops (vieiras in Spanish), creating a savory, slightly sweet, and briny sauce. The count (14/18) indicates the mussel size and quality.
