This recipe works equally well with trout or alternatively a whole trout/salmon wrapped in banana leaves - just extend the cooking time accordingly.
Don't be too liberal with the brushing of oil, keep to area in use as excess oil creates lots of smoke. Avoid using spray oils if you want to keep your eyebrows.
The salmon was delicious! I added about 4 fresh lemon myrtle leaves (finely chopped) to the bowl. I didn't cook the rosti but served the salmon with mashed potato, steamed carrots and broccoli.
I stashed some leftovers (before I served it) so that I can have it for lunch today.
