Longline Mussels
This mussel is bred at sea on suspended ropes. It has a very pronounced iodized taste du to its culture in the open sea. Compared to Bouchot mussels, it is slightly larger in size with a more sustained flesh color.
Since it is permanently kept under water, its shell is also more fragile.
After harvesting, mussels are put in a pool of seawater to remove any impurities. Then nets have to be removed and mussels are cleaned and sorted by hand before packing.
Mussels are calibrated mechanically using a grid so that their thickness is at least 12mm.
Usually packing range is from 5 to 15kg. Mussels can also be packed in plastic tray under a controlled atmosphere for longer storage.
The byssus (from Greek bussos, fine linen) is a set of fibers made by the mussel in order to hang on.
A ready-to-cook mussel (RTC) is a mussel from which the byssus has been removed before packing. Thus you do not have to remove these filaments yourself and mussels can be put directly into the pan!
