Once upon a time, a Miami girl with Louisiana ties wanted to make gumbo for her friends. She searched and searched for fresh crawfish to no avail, so she had no choice but to settle for the frozen variety, which she found somewhere in Homestead. If only our girl had known about Golden Rule Seafood Market. Established in 1943 and family-owned since 1969, this place in Palmetto Bay has a large variety at reasonable prices, including live crawfish when available. The seafood here comes from all over. You'll find local stuff, including stone crab, Key West shrimp, and Florida lobster, but you'll also discover scrumptious goods from South America, Mexico, Florida's west coast, and other locales. Shelves are stocked with every imaginable seasoning and sauce. And periodically, you can attend a cooking demo to learn how to prepare your dinner. Call ahead to find out what's available.
