Test Kitchen Tip: To clean mussels, use a stiff brush to scrub as you rinse them under running water. Discard any mussels with broken shells or any whose shells remain open after you tap them lightly. Use a blunt knife to scrape off any barnacles and pull off the “beard” as you wash them. Once you have debearded the mussels, cook them in short order because they don't live long afterward.
