Mussels

What Are Mussels?

Mytilus edulis - the common or blue mussel is a bivalve mollusc that is found most commonly attached to rocks or other objects well below the tideline.

They feed by filtering suspended particles of food (such as plankton) from the water in which they live - for this reason, they are prone to accumulating toxins and pollutants - so they should only be gathered from clean, unpolluted waters, away from outfalls and densely populated areas.

They were heavily encrusted with barnacles, which I scraped off with my oyster knife, which has a really stout blade that isn't so razor sharp as to present a hazard to the fingers.

Muscular

Now to cook them...

Once the onion had softened, I turned the heat right up, tipped in the mussels and added some dry cider and put the lid on (white wine would have been my preference, but I had none to hand).

I gave the pan a shake every minute or so to make sure they all got evenly cooked.

And they were delicious. The traditional way to eat them is to use an empty pair of shells like tweezers to pick the meat out of the others.

They need little or no additional seasoning - as they contain quite a bit of salty juice when cooked - this combines with the other ingredients to make a tasty broth which is good mopped up with crusty bread.

A Surprise

At first, I thought this must just be pieces of environmental grit they had accumulated, but it wasn't.

It was mussel pearls. Loads of them.

Oh, they're worthless, of course. The largest of them is maybe 4mm across and they're not as lustrous (nor, I suspect, as durable) as oyster pearls, but still, they're quite pretty and interesting.

Mussel Pearls

The pearls were all found embedded in the mantle of the mussels (the bit that appears as an orange outer covering when you're eating them.

They're formed when the mantle is injured or invaded by a microscopic parasite, or (only occasionally, contrary to popular belief) when a grain of sand or grit gets stuck. The animal responds by secreting layers of shell or shell lining material and these build up to form the rounded shape of the pearl.

It stands to reason that the longer the mussel lives, the more likely it is that this will occur - so the huge specimens I gathered were probably not the best candidates for the pot - I verified this by picking some smaller, younger mussels later in the week - and I found these to be almost completely free of grit.

Ah, a man after my own heart.I do this whenever I'm in Hornsea as there are more mussels to be picked than you could possibly eat.One thing though - we always check with the local authority that the water is considered clean enough/pollution free first
