Clean the fish. I cut the fish in half because they were frozen and I didn't have time to defrost them.

Combine the ingredients in a mortar, adding soy sauce and lemon juice at the end

Prepare a pan lined with baking paper. Place fish, smother with the ingredients from the mortar evenly and wrap with aluminum foil. Bake for 30 mins. I baked for 45 mins because the frozen fish took longer to cook.
