This isn’t a classic cocktail it’s just a really good cocktail. The Midori sour is pretty awful drink. If you google it you’ll find many different recipes for it (also trying to improve it) but the official Beam Suntory recipe is half Midori and half sweet and sour mix. It comes in around 10% ABV and taste as bad as it sounds. This late 70s drink reeks of sweaty polyester suits at studio 54 looking to fuck.
This improved one keeps the same flavor and intent as the original, but isn’t as sweet and the herbal flavors make it much more palatable.
