Gomasio or gomashio is a traditional condiment consisting of sesame seeds (goma) and salt (sio). The sesame seeds are lightly toasted before they're used in the mixture. Although gomasio traditionally consists only of those two ingredients, some blends also include seaweed or sugar.
The condiment is traditionally made by using suribachi, a tool that has sharp edges which make it easier to grind seeds. This condiment is especially popular in macrobiotic diets, and it's typically used as a seasoning for plain rice, broccoli, cauliflower, or
sekihan (beans and rice).
