Facts about Mussels
Did you know?
Although some mussels can live for up to 50 years, the brown mussel that we find along the east coast of SA only lives about 2 years.
Pearls are cultivated in freshwater mussels.
You can tell the difference between wild and cultured mussels by looking for the dull bluish colour, white erosion marks and attached barnacles of the former. Cultured mussels have shiny blue-black shells.
The mussel’s arch enemy is the dog whelk, which bores a hole through its shell and sucks out the soft parts.
The mussel’s ‘beard’ is known as the byssus. It is used by the mussel to attach itself to surfaces with the aid of a secreted adhesive cement.
Before preparing a mussel for cooking and eating, the byssus should either by cut off or pulled out with a sharp tug, then discarded.
Mussels are usually prepared by steaming over a medium heat for about six minutes or until the shells open.
Because mussels contain liquid that emerges during the steaming process, you don’t have to add water when you’re steaming fresh mussels.
You shouldn’t be concerned if a batch of mussels is of different colours: pale white meat indicates a male mussel, and a warmer, more orangey colour, a female.
Mussels are a good substitute for clams or oysters in a recipe.
Mussel juice is delicious and can be drunk hot; it’s particularly tasty when mixed with a little melted butter, and can also be consumed chilled with tomato juice.
Although clams and oysters are sometimes eaten raw, mussels are usually cooked. (Note: Except in Africa, where the women and children often eat raw mussels on the rocks.)
While wild mussels need quite thorough cleaning, cultivated mussels need only be rinsed in cold water.
Mussels are delicious when pan-fried, too. To pan-fry, heat the pan, melt some butter then add the mussel meat and sauté until brown – two to three minutes.
Mussels rely on fish to carry their eggs in their gills during part of their life cycle.
Mussels have been cultivated for almost 800 years in Europe, and have been used as a food source for more than 2,000 years.
When buying mussels, the shells should be bright, undamaged and closed. Open mussels should be given a squeeze and a tap – if they close they are still alive; if not they are dead and unfit for consumption.
Mussels affix themselves to substrata such as rocks by their byssal threads or ‘beards’. These are produced as a liquid, which sets in contact with seawater.
The byssal threads are so adhesive they can even cling to Teflon; scientists are trying to develop a mussel-based adhesive for use in eye surgery.
Mussel meat is rich in protein, and has much less fat, many more mineral nutrients and a quarter of the calories of beef.
