How does Hotaru cook the rice, is it boiled?
No, Hotaru does not simply boil the rice.
Hotaru is an Induction Heating (IH) rice cooker featuring UMAI Advanced Fuzzy Logic cooking control. Rather than using a simple boil-and-steam process, Hotaru intelligently controls the cooking temperature and timing through at least seven distinct cooking phases.
This multi-phase approach allows the cooker to carefully manage how heat and water are applied throughout the cooking process, helping to produce consistently excellent rice while supporting the retention of the rice's natural nutrients.
Hotaru's Multi-Phase Cooking Process
The cooking cycle progresses through these key stages:
Preheat – gently brings the rice and water up to the optimum starting temperature.
Absorb Water – allows the rice to gradually absorb water before the main cooking stage.
Heating – increases the temperature in preparation for boiling.
Boiling – brings the contents to the required cooking temperature.
Braising – continues cooking under controlled heat to develop the rice's texture and flavour.
Absorb Water – allows remaining moisture to be absorbed into the rice.
Keep Warm – once cooking is complete, Hotaru automatically maintains the rice at a suitable serving temperature.
Why Does Hotaru Use Multiple Cooking Phases?
Rice cooking isn't simply a case of heating rice and water until all the water disappears. Different stages of the process require different temperatures and cooking conditions.
Hotaru's UMAI Advanced Fuzzy Logic control manages these stages automatically, adjusting the cooking process to help achieve consistent results.
Combined with Induction Heating, which generates heat directly within the inner bowl, this gives Hotaru precise control over the cooking environment.
The result is a carefully controlled cooking cycle designed to produce fluffy, evenly cooked and great-tasting rice, rather than simply boiling the rice until the water has evaporated.
In Summary
Preheat → Absorb Water → Heating → Boiling → Braising → Absorb Water → Keep Warm
Boiling is therefore only one stage of Hotaru's cooking process. The combination of IH heating and UMAI Advanced Fuzzy Logic allows Hotaru to manage the complete cooking cycle intelligently, helping deliver consistently excellent rice cooking cycle after cooking cycle.
