This lovely chap gave us the most in depth and detailed explanation of each of the jams he was selling - where they came from (the fruit all came from areas around Berlin), what they were made of and more. It was almost too much information! And, he had a million types so it was a long visit to this particular stall at the market in central Berlin.
The one funny comment he made was about one of the jams, I think it was a strawberry-rhubarb combination. He said this one was the best as the berries came from Sweden!
