Hot-&-Sour Mussels

Tips:
Bottled clam juice can be very high in sodium. We like Bar Harbor brand, which has 120 mg sodium per 2-ounce serving. Look for it in the canned-fish section or the seafood department of your supermarket.

Chinkiang is a dark vinegar with a smoky flavor. It is available in many Asian specialty markets. If unavailable, white or sherry vinegar are acceptable substitutes.

When shopping for mussels, look for ones that are closed--or those open only a fraction of an inch. When you get them home, store them in a large bowl with a few damp paper towels on top for up to 1 day. To clean them, discard mussels with broken shells or whose shell remains open after you tap it. Hold mussels under running water and use a stiff brush to remove any barnacles; pull off any black fibrous “beards”. (Some mussels may not have a beard.) Mussels should be “debearded” no more than 30 minutes before cooking.
