In Mexican cooking, salpicón is a dish of fish, shellfish or meat mixed with chopped vegetables and tossed in an aromatic dressing. In the Yucatán, salpicones are flavored with sour orange juice and habaneros. In this version, quick-roasted fish fillets are tossed in lime and orange juice to mimic that tropical flavor. The fattiness of the fish and avocado tame the heat of the habaneros, but if you are sensitive to spice, use half of a habanero or look for habanadas, a chile that tastes just as sweet and floral as a habanero but with zero heat! You can serve this dish right away while the fish is still warm, or refrigerate the fish and pico de gallo separately for a few hours — the flavors only get better. Then mix together cold for parties, picnics or a day at the beach.
