Right, this is for 1 serving, though I think it should be served by the bowl full!
Into a shaker/mixed goes cubed ice followed by the Kirsh, White Rum & the Orange, then a dash of lime depending on how sour you like things. Shake the mixer up and pour into a martini glass, now VERY gently pour in the Grenadine Rouge until it turns the color of a Cuban sunset ... and finish with a pair of Marachino cherries one in one out.
