Zuppa di Pesce

Gisa Sotis makes this fish soup with red mullet, which gives it a wonderful strong flavor and a lovely color. Red mullet, triglia in Italy, really isn’t a mullet at all, but a bright red goatfish with firm, tasty flesh. Since the mullet is so difficult to find, I’ve substituted small mackerel, trout, or even shrimp with entirely satisfying results.
