Fresh soy milk flavored with pandan leaf — documented in China since 206 BCE, the Vietnamese street-vendor version distinguished by pandan's vanilla-like fragrance.

Sữa Đậu Nành — Vietnamese soy milk — is a daily staple of the Vietnamese morning food culture that distinguishes it from commercially produced soy milk through its freshness, its pandan leaf flavoring, and its typically lighter consistency. Soy milk as a preparation has been documented in China since at least the Han Dynasty (206 BCE–220 CE), produced by soaking dried soybeans, grinding them with water, cooking the resulting liquid to destroy the antinutritional factors in raw soy, and straining the mixture to remove solids. The technique spread through East and Southeast Asia with the broader diffusion of soybean cultivation, reaching Vietnam through the centuries of Chinese cultural influence on Vietnamese food traditions. Vietnamese sữa đậu nành is distinguished from Chinese or Western commercial versions by the common addition of pandan leaf (lá dứa, Pandanus amaryllifolius) during the cooking process — the aromatic plant's vanilla-like fragrance from the compound 2-acetyl-1-pyrroline infusing the milk with a characteristic Southeast Asian aroma — and by its traditional fresh preparation and street sale rather than commercial packaging. Morning street vendors in Vietnamese cities dispense fresh soy milk from insulated containers, typically alongside bánh mì or xôi (sticky rice), making fresh soya milk a defining element of the Vietnamese urban breakfast experience.
