how long does it take for mussels to open?
Mussels will keep for 2 to 3 days, however, they are best when cooked as soon as possible. Shucked mussels that have not been cooked can be stored in water or their liquor, covered and refrigerated for up to 2 days. If you are cooking mussels in the shell, do not open and remove the mussel from the shell. Wash the mussels with a stiff kitchen brush under cool running water and remove the beard. NEVER eat a mussel whose shell is not open after cooking.
