I made this last night and it turned out decently, although the fish was cut too thick so I had to cook it a little longer. Opah may not be the ideal fish for this, so I’ll try it later with tilapia or other fillet.
1 Tbsp grated ginger
1 large clove garlic
3 Tbsp lemon juice
1 Tbsp honey
1 green chili
1 lb opah
2 sheets parchment paper
2 Tbsp chives
Mix all ingredients other than fish and chives, omitting chili seeds if desired. Marinate fish for approximately 30 minutes (longer will start to cook the fish, ceviche-style). Split fish into two halves and place in parchment envelopes, pouring remaining lemon juice on top. Bake at 400 degrees for 10-15 minutes.
