3 tbsp of milk
1 can of pepsi cola (or coke)
1 bottle of Canadian whisky (or whiskey)
Fill a cup 3/4 of the way with Pepsi or Diet Pepsi. Add in the whiskey until it's about an inch from the top. Stir for 5 seconds. Add in 3-4 spoonfuls of milk. Stir until it starts getting foamy at the top. The foam should rise a bit.
