The German grüne Soße (literally ‘green sauce’) is commonly found in the Hesse state of Germany, including Frankfurt am Main and Kassel. While the guy was doing his stint in Frankfurt back in 2011, we’ve had quite many opportunities to try out this dish, though I must say it did come across as a very strange dish back then because of its name and colour. The weirdest thing is that the sauce is served chilled, and the rest of the ingredients such as the eggs and potatos hot. My mum always told me since I was young that we should not eat things served cold and hot at the same time because it gives us tummy aches!
