Inspired by the memory of perfectly crisp Mediterranean sardines on the Moroccan coast, we turned to smelts—another tasty, tiny fish (rainbow smelts from lakes Erie, Huron and Superior is the most sustainably harvested variety). Just a dredge in flour seasoned with cayenne, cumin and turmeric, and a quick shallow fry is all these irresistible morsels need. For the ultimate snack, serve them hot with lots of lime…and a cold beer or two.
