Bastillepost · 1 SOURCESabout 1 hour ago2 MIN
Summary
A new feature explores how sesame seeds traveled from Africa through Central Asia to China via the ancient Silk Road, transforming from a scarce imported commodity into an essential flavor enhancer in Hong Kong kitchens. The piece traces the ingredient's 2,000-year history from Western Han trade routes to Buddhist temple kitchens and modern day dining tables, revealing how a single drop of aromatic oil encapsulates centuries of cultural exchange and culinary evolution.
Key Points
- Sesame originated in Africa, was domesticated in the Indus Valley, and spread eastward through Central Asia along the Silk Road before gradually reaching Central China .
- Historical records show that by the Eastern Han dynasty, sesame was already cultivated in the Central Plains; Liu Xi's "Er Ya" notes that Emperor Ling enjoyed sesame-seed cakes, prompting the capital to follow suit .
- Sesame oil played a pioneering role in the emergence of Chinese plant-oil cuisine, enabling the "hot wok, cold oil" cooking logic that laid the groundwork for later stir-frying techniques .
- As Buddhism spread eastward from the Eastern Han onward, sesame oil became the primary cooking fat in monastery kitchens due to its fragrant aroma and neutral properties, recorded in works like "Qi Min Yao Shu" .
- From the Song dynasty onward, cheaper and higher-yielding oils like rapeseed and soybean displaced sesame as the staple cooking oil, relegating it to a premium flavoring agent .
- A single drop of sesame oil in a Hong Kong kitchen is the culmination of this millennia-long journey from "Hu Ma" (foreign hemp) to "Xiang You" (aromatic oil) .
