Thai Sticky Rice (Khao Niew)

Description

Thai sticky rice is steamed to achieve a cohesive, chewy texture through amylopectin gelatinization.

Technical

During steaming, the high amylopectin content of khao niew undergoes gelatinization as starch granules swell and rupture at 60‑70 °C, forming a cohesive matrix. The process is driven by saturated steam at 100 °C, which transfers heat uniformly via a bamboo steamer, preventing direct water contact and preserving the characteristic chewy texture. Proper soaking, water‑to‑rice ratio, and steaming time are critical to avoid failure modes such as mushiness or hardness, ensuring the rice’s cultural and culinary integrity.
