Sushi rolls for camping

I woke up early in the morning on the 24th of December to get 16 sushi rolls ready. It was my first time cooking so much rice (1.5 kg) in my whole life. I was very thrilled as everything came together nicely. I got all prep done and  the rolls were ready within 3 hours. I had to do some calculations on how much rice I need to fill 16 rolls (ratio of uncooked versus cooked rice). Basically, 1 cup of uncooked rice  makes 3 rolls. so all I had to do was used my basic maths and do the multiplication. I kept the fillings simple- tuna mayo, carrot, cucumber and sesame seeds.

Recipe for the rice can be found from an earlier post here.
