The Blue Lagoon is a French cocktail featuring blue Curaçao mixed with vodka and lemonade. It is typically garnished with an orange slice or a lemon slice. A Blue Lagoon is typically served in a hurricane glass.
Harry's New York Bar in Paris claims to have invented the drink.
One variation adds a dash of lime cordial to the mix. Another variation with a dash of raspberry cordial or grenadine is known as a "fruit tingle", after the Australian candy of that name.
In Denmark, the drink is known as an "Isbjørn" (polar bear).
