I've never met anyone who cooks rice by boiling the water first. Maybe it's an Indian thing, but all the people who've ever shown me 'the right way' to make rice in SE Asian cooking, stretching from Japan to Vietnam, rinse the rice a few times and then cook it from cold. The 'trick' for good rice is using the right amount of water and adjusting the heat to a low simmer when it boils.
My (Asian) wife adds that she's heard of it but 'we thought that's how white people like rice.' ¯\(°_o)/¯
"After it was ready, we let it cool in the refrigerator for about 12 hours. That's it."
Again, who eats their rice ice-cold unless they got take out the previous evening? Rice isn't that nice cold, nor is it absorbent enough to mop up sauces with, which is sort of a key thing in most Asian cuisine because it's always consumed as an accompaniment to something else, no matter how basic.
