I saw this interesting mixer or spinning device in the kitchen at the Platypus Bogota Hostel. You place it between your palms and rub back and forth making it mix. This Colombian girl was using it to mix hot chocolate.
German the owner being personal and talking with guest.
There are large hills, maybe mountains behind the city. There is a trolley that goes up steel cables of this hill.
The mixer is a "molinillo." Introduced by the Spanish.
Sorry to post a commercial URL but it seems to have the handiest small history.
We have these wodden tools in germany, where they are called "Quirl".
I always wondered why I never could find it in the US. It is such a simple tool.
Sounds great for hot chocolate!
