Fresh, sweet, delicious, scallops, straight off the boat. A scallop boat is only allowed to fish approximately 60 days per year, so fresh off the boat (never frozen) scallops are scarce.
U15 scallops are no more than 15 per pound, and thus about 1 ounce each.
U10 scallops are no more than 10 per pound, and thus are 1.6 ounce each.
Buying a quantity of "1" is a purchase of one pound of fresh, never frozen, local, delicious scallops.
