The Chi Chi is essentially a vodka Pina Colada. Vodka is fairly neutral so clean pineapple and coconut flavours are not shadowed. The ratios below were featured in The 12 Bottle Bar book - it's fairly heavy on the cream of coconut (or as they refer to is as coconut milk syrup) compared to other recipes which call for half the cream of coconut and up to double the pineapple juice. If you aren't a sweet tooth, opt for the later.Learn how to make your own DIY Cream of Coconut here for better tastying Pina Coladas (and Chi Chi)!
