Pepes ikan is pretty popular in Indonesia. It is also my preference of serving fish as it is pretty aromatic and I love the exotic and rustic look how this dish presented at the table. 

I don't think there is a standard recipe for this dish, every household seem to have their own version of pepes ikan. The recipe that I use here is based on how my mom used to make it. I remember she loved to add tons of basil leaves for this dish. I used to hate it, but I really love it now. Sometimes she would grilled the fish after it being steamed, but most of the time she simply steamed it.

Make Balinese spice paste, then divide it into 4 portions. 

Lay 2 layers of banana leaves on a counter top, spread one portion of spice paste on top, add a sprig of basil, piece of kaffir leave, and 4 slices of tomatoes, then lay tilapia on top. Spread another portions of spice paste directly on top including the cavity, add another sprig of basil, and another piece of kaffir lime leave. Wrap and secure both ends with tooth picks.
