In Taiwanese households, there is an essential cooking ingredient that is always stocked alongside soy sauce, vinegar, and sugar. It’s not fermented bean sauce, XO sauce, chili sauce, or fermented bean curd, but rather, shacha sauce.
Sold in metal tins or glass jars, shacha sauce looks dark brown and shiny. When eaten, it has a sandy, fibrous mouthfeel. Although its contents remain a mystery to many, its salty, umami flavor has captured the hearts of Taiwanese people.
