If the city of Chicago had an official drink of summer, it would likely be the Negroni Slushy. The frosty Negroni Slushy burst on to the cocktail scene when Parson's opened its doors. Parson's is known for their sprawling sunlight patio with red and white striped umbrellas filled with hipster sipping Negroni Slushies and eating fried chicken.
One of the best things about this recipe is that you can prepare the Negroni Slushies in advance! Just blend them up and pour into a container, cover, and put in the freezer. Use a fork to break up the iciness that forms and serve. This recipe serves 4, and it really is the maximum amount that you should put in a blender. So if you want more than 4 servings, make them in multiple batches.
