Happy National Whiskey Sour day! Although, it is a national day in US, I do see no reason even for us to celebrate and have a nice whiskey sour. Although the classic recipe is one of my favorite and most preferred cocktails, I also enjoy making and having different variations of it. Milk clarification is one of my favorite techniques, so I wanted to make a clarified New York sour for this special day. You can prepare any variation of a whiskey sour before the clarification, that is totally up to your taste.⁣
