First, this is not a cocktail. It is a shooter. Second, it is very potent. It has Cinnamon Scnapps which is nearly 100 proof and 1800 Silver Tequila which is also 100 proof. Garnish with a cinnamon stick.
This is a variation of the traditional Sidecar. Instead of cognac, you use Tap 357 which is an unique maple whiskey (made from rye and maple) from Canada (Quebec, if I am not very mistaken). The other two ingredients are Cointreau and lime juice.
