Step #8 Cut the fish into 3- by 1-inch batons & place this in a ceramic or glass bowl.
Step #9 Add 6 tbsps of the chile paste & mix together carefully but thoroughly.
Step #10 Cover & put in the fridge for 1 to 2 hrs.
Step #11 Separate out 18 of the largest & most pliable husks, at least 6 inches across on the wider end & 6 to 7 inches long.
Step #12 If you cant find enough good ones, overlap some of the larger ones to give a wide & strong unbroken surface to spread the dough on.
Step #13 Pat the leaves dry with a towel.
Step #14 Make ties for the tamales by cutting a few of the husks into strips.
Step #15 Divide the marinated fish into 6 equal portions.
Step #16 Spread 1 tsp of the reserved chile paste over a 2- by 3-inch area on the wide end of a husk.
Step #17 Lay half of one portion of fish over the paste.
Step #18 Sprinkle top with a little salt & top this with the remaining half portion of fish.
Step #19 Fold over the sides & then the ends to enclose the filling.
Step #20 Lay the finished package flap side down, repeat the operation to double wrap the fish & tie it twice around its width with the cornhusk strips.
Step #21 Continue to form the other 5 packages in the same way.
Step #22 About 20 mins before serving, heat a large griddle or a grill to medium-high heat.
Step #23 Grill the packages for about 6 mins on each side, until the husks have blackened.
Step #24 Open one of the packages to test for doneness, taking care not to let out any of the precious juices.
Step #25 Remove the strings from each package & carefully pull away the outer layers of husk.
Step #26 Set each package on a heated dinner plate & carefully remove the last husk, pushing the fish out onto the plate.
Step #27 Drizzle a little olive oil over the fish & scatter with a little onion & sliced cilantro.
Step #28 Serve the lime wedges on the side.
Step #29 Pass warm Corn Tortillas, mashed avocado, sliced cucumber, & chiles at the table.
