Glutinous or sticky rice (khao niaw) — the staple grain of Northern Thailand, Laos, and much of Southeast Asia — is fundamentally different from jasmine rice in its starch composition and therefore its cooking technique. Thompson's documentation establishes that sticky rice cannot be boiled in the conventional sense — it must be soaked and then steamed, and attempts to boil it produce a gluey, waterlogged result.
Glutinous rice soaked in cold water for minimum 4 hours (overnight preferred), drained, and steamed in a bamboo basket over boiling water for 20–25 minutes, flipped halfway through. The finished rice should be tender, slightly sticky (grains cling together when pressed), and slightly translucent.
- The soaking is non-negotiable — glutinous rice starch (almost entirely amylopectin, compared to jasmine rice's mix of amylose and amylopectin) does not cook evenly without pre-hydration. Unsoaked sticky rice produces hard, undercooked centres [VERIFY soak time] - Steam, never boil — boiling washes out the surface starch and produces a waterlogged, gluey mass. The steam hydrates without over-saturating - The bamboo steamer: the woven structure allows steam circulation on all sides simultaneously. A metal steamer with a tight base produces uneven cooking [VERIFY] - Flip halfway through steaming — the bottom layer in contact with the steam cooks faster than the top. Flipping produces even cooking throughout [VERIFY timing] - Keep warm in the bamboo basket with the lid on — sticky rice hardens rapidly when cold. Traditional consumption involves keeping the basket warm throughout the meal
