Transfer rice into a large bowl, then add rice vinegar, sugar and salt, and mix thoroughly.
Spray 1/4 cup measure with coconut oil then grab small amounts of rice and push into 1/4 cup measure to create circular rice cakes.
Really pack the rice in tight, let it sit for 30 seconds then tap to release.
You should be able to make at least nine rice cakes.
Once you have moulded your rice cakes, heat two tbsp of sesame oil in skillet on high heat.
Carefully place rice cakes into skillet, do not move them around too much, you want to create a crisp layer.
Once a crisp layer has formed, add another two tbsp of sesame oil and turn to crisp the other side.
Remove rice cakes once crisp on both sides.
