Food - special mention for Peruvian potatoes

There are over 4000 varieties of Peruvian potatoes grown in the Andes, we were told several times. This is difficult to believe at first but as we encountered an increasing number of them in meals and saw so many colourful-flowering potato plants in fields, and an inumerable amount in the markets, we reckon their claim could be correct. Dishes of potatoes, illustrating a few of the shapes and colours grown. The potatoes at the top left are incredibly light due to them having been dried, this was traditionally a way of storing potatoes for years if need be. Simon had a nice dish made of dried potato in Cusco. The bowls on the right contain some kind of clay made by grinding the stone-like substance together with water. It is eaten as an accompaniament to the black potatoes and tasted surprisingly good (see below).
Curious but yummy
