On a hot summer day, nothing beats doogh, a yogurt drink with small cubes of cucumber and mint. Much like a lassi but less sweet and sometimes carbonated.
In the traditional form it is much like Kefir that way, however there are now versions that have carbonated water added to the yogurt. I find the latter unpalatable.
I reread your posting and realized the first time I read it I assumed it was a (coca-) cola flavored drink with additional cucumber and mint flavoring added.
Here in Chicago only carbonated soft drinks (soda pop) with cola flavoring in them are referred to as a cola drink, usually called a “coke”.
If you asked for a “coke” or a cola and the restaurant didn’t carry Coca-cola they might ask if the brand Pepsi was ok
but they certainly wouldn’t confuse your request with requesting a lemon lime soda pop, root beer soda pop, orange soda pop, et cetera.
Somethings do get lost in translation. That’s why interpreters call themselves interpreters instead of translators. There’s usually culture to be dealt with.
