Mussels in cream is a traditional dish originating from Ireland, and it's especially popular in Donegal and Cork. Although there are many variations on this simple dish, it's often made with a combination of scrubbed and debearded mussels, butter, heavy cream, flour, salt, and pepper. The mussels are heated in a skillet until the shells open, and any unopened mussels are discarded. A roux is made from butter and flour, and it's then mixed with a bit of water and heavy cream until the sauce thickens. The sauce is seasoned with salt and pepper and it's then mixed with the mussels and their juices. The dish is stirred well in order for the mussels to be coated with the sauce before serving.
