3.2 oz. mccormick vodka Place into container
In measuring cup:
1/2 tbps lime concentrate (i used reallime brand)
3/4 tbps lemon concentrate (i used great value brand)
Add unflavored seltzer water to make 8 oz. (i used the walmart brand, but ingredients "carbonated water" do brands really matter at this point?)
Pour the mixture into the container and mix it up. It doesnt look like zima - the lime and lemon make it foggy. but to the best of my recollection, 4 years later, this is in the ball-park.
I know this isnt what the original poster was looking for at all, but i was searching google for a mixed drink to replicate Zima, and this thread was one of the top posts, failing to find any information, i expirimented and found this recipe, so for people searching what i did, you should find what you are looking for.
P.S. sorry for any bad grammar, or redundancy, i have had 2 of the final product, plus all of the failures trying to get there - were partial servings, but there were like 8 of them, so im not in the condition to write a gramatically correct post.
