Olive Oil is an unusual but intriguing cocktail ingredient, often used to add a smooth texture and a hint of savory flavor to drinks. It’s typically incorporated into cocktails through a technique called fat-washing, where a spirit like gin or vodka is infused with olive oil and then frozen to remove the fat, leaving behind the oil's subtle flavors. Olive oil can also be used as a surface garnish, adding a luxurious mouthfeel and a slight vegetal taste that pairs well with herbal or citrus-driven cocktails. This ingredient is especially popular in modern mixology, where bartenders are pushing the boundaries of traditional cocktail flavors.
