In some parts of Kerala, the father's sister is called "Mema". My sister-in-law made this drink for my son during our visit to India. So, anytime he's asked what he'd like to drink, his answer is "Mema's cola-float". He adds a prefix to a lot of things...like Achamma's light coffee, Amamma's fish fry and so on.
This is kid friendly and they enjoy it all the more since they make it own their own. Just pour a can of cola into a glass and drop a dollop of vanilla ice-cream into it and the drink is ready!!! A nice treat on a hot summer day.
