Sake Bomb is a Japanese cocktail that is prepared by dropping a shot glass filled with sake into a glass of beer. Traditionally, the sake shot is balanced on two chopsticks which are placed on top of the glass of beer. The consumers should slam the table with their fists, causing the shot to drop into the beer, and the cocktail is then drunk immediately.
Although the origins of Sake Bomb are quite murky and the drink is often associated with Japan, it is also believed that the drink was actually invented by American soldiers who were occupying Japan after World War II, and that is the reason why the cocktail is much more popular in America than it is in Japan.
