Often the last thing people in the North and Northeast of Thailand do before bed is put raw grains of sticky rice in a pot, cover them with water, and leave them to soak. This is sticky rice country, and a day without sticky rice is almost unthinkable.
Also called glutinous rice, it has a different starch composition than varieties like jasmine. I'm not qualified to explain the world of amylopectin and amylose starches, so suffice it to say that the glossy cooked grains of sticky rice are particularly chewy and stick to one another in clumps, yet still remain distinct. It's a magical thing. Served in baskets, either one per person or as a mountainous mound to be passed around, the grains of sticky rice form moldable masses. Practiced diners snatch off a gumball-size piece, reflexively fashion it into a sort of spoon shape, and use it to grab a taste of whatever else is on the table. In these baskets or in bamboo tubes, workers carry this rice with them into the fields and forests, a portable, edible eating implement.
While you could argue that so-called "steamed jasmine rice" isn't steamed at all but rather boiled, sticky rice is actually steamed. In the Northeast, it typically goes into a bamboo basket; in the North, it's traditionally prepared in a clay pot with a perforated bottom, though today the pot is often aluminum. The basket or pot is set over a pot-bellied vessel filled with boiling water and the steam cooks the grains, already swollen from soaking, in just 15 minutes or so. The process is easy enough for uninitiated cooks. It just takes a little practice to get right.
