To a small saucepan, combine the sugar and water. Heat over medium-low until sugar has dissolved. Add the sage leaves and ginger and cook for an additional 5 minutes. Turn off the heat and allow the sage and ginger to steep for 15-20 minutes. Strain, discarding the sage and ginger; set aside.

To assemble a cocktail, fill a glass with ice. Pour in 1 ounce of the sage-ginger simple syrup (2 tablespoons), 2 fluid ounces vodka, 5 ounces pear nectar. Stir and adjust alcohol to your taste. Garnish with a slice of small pear. Repeat the drink-making process until you've made all four. Serve immediately.
