Place rice and butter in a saucepan over a medium high heat with the water. Bring to a boil, reduce heat and cover, simmer until all liquid is almost absorbed.
Then turn off heat and leave, the steam trapped underneath will continue to cook the rice.
Allow rice to cool and then you can roll into balls.
Add the coconut aminos, water, sesame oil, maple syrup, spring onion and a sprinkling of sesame seeds to a bowl and whisk together.
Enjoy the rice balls dipped into the sauce.
These are great for lunch boxes, as they are served cold.
