Preheat the oven to 170 degrees
In a small bowl, add in the sesame oil and tamari and mix
With a pastry brush, brush on the mixture on the shiny side of the seaweed all the way to each edge
Sprinkle with sesame seeds and cover with another sheet of Nori - shiny side down and press firmly together
Repeat to make 4 lots of double sheets, using up all of the Nori sheets
Place onto a lined baking tray and cover with another layer of baking paper. Place a glass baking dish over the top to use as a baking weight or something similar to hold down the baking paper so that the seaweed sheets don't curl up when baking
Place into the oven and bake for 10 minutes
Remove from the oven and set aside to cool slightly for a minute or so before slicing into pieces with scissors
