I adapted this from drinksmixer.com. Be careful...it goes down a little too easy! (The original recipe uses cream instead of milk...feel free, but I have dietary restrictions so I can't have that much fat in a drink!)
Add a few ice cubes to a highball glass. Pour in liqueurs and drop in a couple maraschino cherries (I add a little of the cherry juice, too). Pour the cream down the sides of the glass and stir lightly before serving.
You can also hold the cherries out, top with whipped cream and cherries.
