This recipe is almost exactly the recipe from a restaurant that I ALWAYS order the mussel appetizer when I go there! I found this recipe on the copy cat website and am sooo thankful! These are absolutely divine!
When melted, remove from heat and set aside for several minutes to allow the milk solids to settle to the bottom.
Skim the clear (clarified) butter from the top and discard sediment. (This can be done ahead.).
Now make the sauce for the Mussels:
Heat clarified butter.
Add onion and garlic and saute until transparent.
Add lemon juice and white wine and season to taste with salt and pepper. Simmer 2 to 3 minutes to reduce liquid.
Remove from heat and swirl in remaining 2 tablespoons cold butter until sauce is smooth and emulsified.
Soak mussels in cold water for several minutes, then scrub with a stiff brush and remove "beard" (the little tuft of fibers protruding from the shell), either with a sharp knife or by pulling on it with a damp cloth.
Rinse mussels again in cold water.
Heat olive oil in a 10-inch skillet; add mussels.
Cover with another 10-inch skillet or lid and cook until shells begin to open, about 2 minutes.
Remove top and add onion and garlic and toss.
Cover pan again and cook for 1 minute.
Remove top and add pernod, basil, lemon juice and lemon butter sauce.
Return to flame for 30 to 45 seconds with top off skillet.
