I saw this one in e-recipe. I meant to make a similar dish with cheese but I thought this was very interesting and perfect for using up the left over mochi 餅 or rice cake from New Year. I made this one weekend as a starter dish. Since I did not have spring roll wrap or skin, I used an American style square “gyoza” or wonton skin instead.
The inside has mochi wrapped in a seasoned nori sheet which was smeared with yuzu-koshou 柚子胡椒. I served the rolls on a bed of baby arugula. I poured a small amount of the peanut oil in which the rolls were cooked plus a splash of soy sauce over the arugula to make an impromptu dressing and to slightly wilt it.
Mochi: I cut a square of mochi or kiri-mochi 切り餅 into 5 equal size sticks.
Using a small non-stick frying pan with peanut oil (1 tbs) on low heat (#5). I turned them every 30 seconds or so initially so that all the overlapped skins got cooked evenly and held together (#5). Once all the sides were fried, I let it cook a longer time on one side (1 minute or so on each side) until the skin was brown, crispy, and the mochi was soft (total of 5-7 minutes). When I saw soft mochi starting to come out from the seam and knew it was done (see the very first picture in the beginning of the post).
