In South Africa we have one kind of Sour Cream and that is pretty much it... Here in Bosnia they have many different kinds of sour cream, from 12%, to 20%, to 40% and about every kind of size you can imagine, up to 1kg! They really like their sour cream here, and have it with pretty much EVERYTHING: including pizza!
To give you an idea of the importance of sour cream...here is a pic of the shelves in the fridge in my local LITTLE supermarket. Except for the bottom layer which are milk and drinking jogurt and on the left you can see little chocolate and strawberry puddings, this is ALL JUST SOUR CREAM!!!!
