This is usually served as a layered shot. Add 1/2 oz "Peach flavored Bourbon" (SoCo, typically), 1/2 oz Amaretto, finally 1/2 oz Cranberry juice. Use a spoon to layer if necessary.

Add a splash of lime juice or lime garnish if you like... try it with and without, it changes the flavor noticeably.

Get it all in your mouth at once, no sipping.
