Wash apples, cut and chop, leaving skin on.
Place apples into a medium sized pot.
Add in the sugar and water, stir and bring to a boil. Boil for 6 minutes or so, just until the apples start to become tender.
Using a potato masher, mash the apples. Let the mixture sit for 30 minutes or until cool.
Strain out the liquid, pressing on the solids to get every drop out.
At this point you can place the Green Apple Simple Syrup into a sealed jar and store in your fridge until ready to use.
When ready to assemble the drink, combine the Green Apple Simple Syrup, the vodka and the DeKuyper Sour Apple Pucker in a pitcher or pot and stir until combined. Use a 1 to 1 to 1 ratio. 1 cup of each for example. adjust to your preference of sweetness or alcohol strength.
This will have a light green hue from both the Green Apple Simple Syrup and the Pucker. If you want it a bit more vibrant, take 1/2 cup of the mixture and add to it 2 drops of green food coloring, stir vigorously until combined. Strain that back into the jar/pitcher and mix until combined.
Taste and adjust.
This is strong, it's supposed to be. It's not really a cocktail, its more of a fun shot or a martini. For a cocktail, serve it over ice and top with club soda.
Chill and serve in shot glasses. I like it in the freezer an hour or so before serving. You could also use a cocktail shaker filled with ice and shake and pour. Your call.
