Fat-Washing your way to Great Cocktails

A resource used by mixologists to create, great cocktails with fat-washing brings a serious depth of flavor. Check out the many ways you can do this.

Fat washing is when fat (such as oil or duck fat) is added to alcohol and left to soak or infuse, for hours or as strong as you want the flavor. It’s like a bath for your booze.
