A pineapple and coconut delight for hot days, the Chi-Chi is a wonderful tropical cocktail that is something a little different than the average Margarita and Daiquiri. The blue color comes from the curacao and the flavor is very similar to a Pina Colada. Think of it as the blue, vodka version!
Also, I tried this with one of the new coconut vodkas as suggested by a reader and it is fantastic. There are many more possibilities for flavored vodkas as well. I might try raspberry, citrus or one of the whipped cream vodkas.
