Greenshell Mussels with Herbed Breadcrumbs, Au Gratin – Makes an Elegant Appetizer

In North America, blue mussels, the most common variety, grow on pilings, bulkheads, piers, and even on some bridge anchorages. The aquacultures mussels (like those in Europe) are grown on ropes suspended in the water. Blue mussels are harvested from the clear sea waters off the New England coast, while a relative also grows in the northern waters of the Pacific.

New Zealand green lips are larger than blue mussels, with a shell color that ranges from brown to green. Their flavor is more pronounced than blues. Prince Edward mussels are also at fish markets, they’re aquacultures in Canada and Nova Scotia, smaller than the New Zealand variety, and seem to have a more delicate flavor.

I love mussels in lots of different ways but I find this to be very tasty and it also works very well with clams. If you wish, you can add pesto to the breadcrumbs, which will give a lovely flavor to the mussels.

    You know quite a lot of facts about mussels! I am always amazed at people who are able to tell the difference between different types of shellfish, for instance, oysters (which, also, usually differ by geography) – just by looking at them. I love all shellfish, and this recipe looks lovely!

    Oh dear, I love this! It reminds me of our good times at our friend's waterfront property, when we just go to the shore, pick some oysters and bake it over the fire… mmm…

    I love mussels and these are really elegant appetizers. 🙂 These green lips ones are gorgeous. It think I usually see the blues here in the States. 🙂 Hope I can find some of these green lips ones to try.
