3/4 oz Dry Gin
3/4 oz Calvados
3/4 oz Apricot Brandy
3/4 oz Cointreau
3/4 oz Orange Juice
2 dashes Grenadine
stemless Cherry (for garnish)

Boxcutters, Jigger, Shaker Classic/Boston, Citrus Juicer, Strainer, Martini Glass.

Place all ingredients-except the cherry and grenadine-in a cocktail shaker half-filled with ice. Shake vigorously until well-chilled (20 seconds or so).
Strain the contents of the shaker into a Martini Glass, preferably one that's been chilled. Drop the cherry into the glass (it'll nest on the bottom). Add a couple dashes of grenadine-it will flow to the bottom of the glass, enveloping the cherry (see pictures).
