Method: Mix the boiling water with a package of green apple jell-o. Allow the jell-o to dissolve for 1 minute. Add chilled DeKuyper Sour Apple Pucker schnapps; stir until well combined. Pour into 1-oz disposable shot glasses which can be found at most party and food supply stores. Refridgerate for several hours until jell-o sets. Makes about 20 shot-sized servings.
