Lima city water can be drunk, and there is no recycling, so if you insist on buying spring water in plastic bottles you are truly accelerating your contribution to global warming. And Peru is famous for food, so I am going to list some of the foods I encounter constantly.

The Latin American world is very faithful not only to Nescafé but also to preserved forms of milk. In Brazil it is powdered milk, and here it is condensed milk. There is fresh milk, and also pasteurized “long life” milk, and I buy these, but everyone wants condensed milk.

Those CHUÑOS do not agree with me – although I don’t know whether it’s their fault.

Supposedly the issue with the CHUÑOS was an issue about cooked milk.
I am also not really convinced I like CUY.
I have rediscovered how wonderful real Coca-Cola is – or Peruvian Coca-Cola. In small amounts, as a delicacy. It is not like U.S. Coca-Cola, and it is very different from Diet Coke … and it reminds me of the Coca-Cola we used to get in small bottles in Spain.
Shredded chuño used is used in the batter for a fried calamari or in a pollo apanado and it comes out marvelous. The best way to eat cuy is in a pachamanca.
