Translation of concoction in Spanish

We made a little walk into the main street of the town and were looking for a nice place to eat. This time we settled for an Indian restaurant close to the restaurant we were a night earlier.
Considering that the lake was full of crocodiles we gave in to their demand and bought a can of Coca Cola. It cost us two dollars, and considering Cambodia's wholesale price they got plenty of markup.
We left town and drove around the lake. Around 30 minutes after leaving we had a flat tire, which I changed immediately. That was very annoying as the rental company asked us to fix the flat tire.
