Firstly, prepare your home-made Blackberry syrup! In a pan, combine your washed blackberries and sugar. Put on low heat. After the fruit turns mushy, add a squeeze of lemon juice and if needed, some water if the syrup looks too thick. Turn off the gas when you get the syrupy consistency and let cool. Set aside.
Next, prepare your Mint and Green-Apple concoction. Mint gives a fragrant flavor to any cool drink as well as gives a lovely green color to this particular slush. In a blender, combine your Green-Apple juice, mint leaves and fresh lemon juice to a uniform liquid. Set aside. Add sugar if needed.
Next, freeze both of your home-made liquids in separate ice trays for 5-6 hours.
When you are ready to prepare your Mocktail, blend each of your flavored ice-cubes separately with equal quantities of Soda. You will get separate jars of 2 flavors of icy slushes- Blackberry slush and The Green-Apple & Mint Slush.
To assemble your Slush Mocktail, carefully pour both your slushes one after the other into wine-glasses or regular glasses. Insert a straw and serve immediately without mixing! Enjoy!
