Mussels are a Belgian staple - cheap and abundant, they were originally considered a poor man's meal, and have been paired with fried potatoes for a long time at the country's famous friteries (fry shops). It is believed that the dish is originally from Belgium, because Belgians were the first to pair the mussels with fries, commonly eaten throughout the country in wintertime, when no fish was available. Today, the dish is found in most restaurants where it is often shared amongst groups of consumers.
How to Cook:
# In a large Dutch oven or straight-sided 12-inch saute pan, heat the olive oil over medium heat. Add the shallots and garlic and cook until softened, about 2 minutes. Add the white wine and bring to a boil. Season with salt and pepper. Add the mussels, cover and steam until open, about 3 minutes. Using a slotted spoon, transfer the mussels to a large serving bowl.
# Add the creme fraiche, parsley, butter, chives and mustard to the remaining cooking liquid and bring just to a boil while stirring to combine. Pour the sauce over the mussels. Serve with French fries.
