Olive Oil

While olive oil makes an appearance in Richness, like mustard oil it deserves a short mention in this section. One unexpected thing I learned at an olive oil taste testing was that olive oil can create a burning sensation in the mouth. A bottle of fresh olive oil will leave a burning, peppery taste at the back of your mouth due to the presence of oleocanthal, a compound that irritates the sensory receptors. The fresher the oil, the stronger the sensation.
