My friend Beverly, a lifelong Rhode Islander, moved to Denver a couple of weeks ago, leaving behind The Ocean State and its glorious and abundant seafood. For our last dinner on my back porch, I made this seafood stew, filled with all of the good things that come from our coastal waters. The key to the stew is the light broth, which will happily accept almost any type of shellfish or non-oily fish. Best of all, you can make the broth ahead of time, and refrigerate or freeze it. Then, head to the fish market, pick up a selection of seafood, and finish the stew with just a few minutes of cooking. (Remember to ask your fishmonger for some clam "liquor", which most markets will have on hand. The taste is much cleaner than bottled clam juice.) To make the full recipe, the large quantity of seafood will be expensive, so this is a great party or special occasion dish. However, you can freeze the broth in small batches, then make just enough for weeknight dinner with any little bits of fish or shellfish. Serve this dish to people you love, especially if they're moving inland.
