So yummy drink. It's a little bit sweet. Next time I may use less maple syrup. From The Framed Table (http://theframedtable.com/2012/09/calvados-maple-syrup-cocktail/)
In a cocktail shaker, combine the calvados, maple syrup, lemon juice and ice and shake for 10 seconds. Strain into glass filled with ice and add the green apple slices as a garnish.
