4 6-to 8-ounce mahi-mahi fillets
1/4 Cup Achiote paste
2 Tbsp fresh orange juice
2 Tbsp fresh lime juice
2 Tbsp Traditional White Balsamic Vinegar
2 garlic cloves, minced
1 tsp Dried Mexican Oregano
1/2 tsp Coarse Kosher Salt or Sea Salt
1/2 tsp Ground Black Pepper
2 3-foot-long pieces of banana leaves
2 Tbsp Extra-Virgin Olive Oil
1/4 Cup dry white wine
4 Bay Leaves
4 pinches of Dried Epazote
2 plum tomatoes, thinly sliced
2 limes, thinly sliced
serve with fresh salsa and pickled onions
Place fish in 13x9x2-inch glass baking dish. Whisk achiote paste and next 7 ingredients in medium bowl. Pour achiote mixture over fish; turn to coat. Cover and chill 1 hour.
Prepare barbecue grill (high heat). Brush shiny side of banana leaves with 2 tablespoons oil; place each on baking sheet, oiled side down (some of leaf will hang over edge of sheet).
Arrange 2 fillets, with marinade still clinging, crosswise in center of each banana leaf, spacing 2 inches apart. Drizzle wine around fish in leaves. Top each fillet with 1 bay leaf and 1 pinch of dried epazote. Fold overhanging edges of banana leaf over fish to enclose loosely.
Transfer fish from baking sheet to grill, folded edges up. Cover and grill until fillets are just opaque in center, about 10 minutes.
Open banana leaves. Transfer fish to plates. Garnish with tomato and lime slices. Serve with fresh salsa and pickled onions.
