1. How to wash rice.
First pour mineral water and stir 2-3 times, then immediately drain the water away. At this point, the rice absorbs mineral water. Scrub the rice rhythmically, pour & drain tap water 4-5 times, and scrub untill the used water becomes clear. The used water is full of nutrients, so you could also use it as a fertilizer for plants.
2. How to soak rice.
After the used water becomes clear, pour mineral water again, and soak the rice. The time length is crucial. The harder the rice, soak longer. Let the rice absorb water full of minerals.
Standard time length: in warm season, approx. 30 minutes / in cool season, approx. 2 hours(when cooking new rice(which contains more water), shorten the time)
3. Steam cooked rice for 15 minutes.
This will form up the rice grains, make Crab Holes (vapor passes through these holes), and make each rice grain shine. The rice will be cooked pure white, with perfect softness and sweetness. Mineral water brings out the original deliciousness of rice.
