While the basic tastes - sweet, salty, sour, bitter, and umami - are well-established, oleogustus is gaining recognition as the sixth taste. Derived from the Latin words for "oil" and "taste", oleogustus refers to the distinct flavour profile of fatty acids. Unlike the other tastes which are typically pleasing, the raw taste of fat can be perceived as unpleasant in isolation. But when skillfully incorporated into dishes, fat transforms into a carrier of flavour, richness, and texture.
