For those who want to turn rice porridge into jelly: Simply add it to hot rice porridge and blend it in a mixer to easily make smooth rice porridge jelly. Transfer it directly into a dish, and it's ready. It solidifies at 70°C, so no cooling is necessary. It firmly sets even with a small amount of additive. It is not significantly affected by temperature changes or the passage of time. Not only can it be used with starch-containing foods such as rice porridge, but it can also be used with other ingredients. It can be made in advance and stored frozen.
