It's called slush since the consistency is just that, slushy! All the ingredients, including the alcohol are mixed together. Then, 7-UP or in my case, I used Squirt is added just before serving.
1 - 12 oz. can frozen lemonade concentrate
1 - 12 oz. can frozen orange juice concentrate
1 cup brewed tea (standard black tea)
2 ½ cups vodka
½ cup sugar
3 ½ cups water
Mix all the ingredients together and freeze for several hours (stir periodically) before serving.
Add a small scoop of the slush mixture to your favorite glass, add 7-UP or a mixer of your choosing.
