Sesame Goma Processing and Sesame Products Hierarchy

Japan — sesame cultivation since the Yayoi period through Chinese influence; sesame oil production established in Nara period; suribachi grinding tradition throughout Japanese culinary history

Japan uses sesame (goma) in a remarkable range of forms, each with distinct flavour profiles, applications, and processing levels. The sesame hierarchy from least to most processed: raw white sesame seeds (shiro goma, very mild, used for salads); lightly toasted white sesame (iri-goma, aromatic, used for finishing); deeply toasted black sesame (kuro goma, bitter, intense, for wagashi and rice); neri-goma (sesame paste, stone-ground raw white sesame to a thick paste similar to tahini but with a distinct Japanese character); pure sesame oil (extracted from roasted sesame, the finishing oil of Japanese cooking); and blended sesame oil (Chinese-style dark toasted sesame used in gyoza dipping sauce and ramen). Understanding which form is appropriate to each application is fundamental to Japanese cooking.

White toasted: mild, warm, nutty; black: bitter, intense, complex; neri-goma: rich, creamy, roasted; sesame oil: aromatic, warm, deeply toasted — each a distinct sensory register
