An intro on German food and my first cooking class

I did it, I finally started! No, not a diet but giving cooking lessons.
My first attempt at it took place the past weekend with a group of fellow Couch Surfers and we concentrated on German food. Being living in Bonn since more than 5 years now, I think I owe this country some gastronomic interest. I haven't been eating traditional German food very often in these years, mostly because there aren't many restaurants around here that serve this kind of food. German food is mostly a homey kind of food, mostly had for dinner with free flowing bier; the kind of food that Gordon Ramsay will push on a nearly failing restaurant in one of his rescue missions. The food around here is instead mostly Italianised, or Turkish at times; naturally we got our Japanese, Chinese, Thai and now also Tibetan joints but you know these places, they all end up having a shared menu across Europe.
Germany is mostly known for 3 ingredients that make up a typical meal: potatoes, pork and sauerkraut. If French cuisine is a majestic ode to eggs, I believe the German one is to potatoes. Mastering them means mastering two of the main ingredients in our pantry (wheat is mostly exploited in Italian cuisine I believe).

The pistachios post

We in Sicily are quite blessed by the production of yummy almonds and pistachios. The city of Agrigento has a festival for the blossoming of the almonds tree that grow in its countryside and in the Noto http://en.wikipedia.org/wiki/Noto valley. Pistachios are instead grown on the sides of the Etna volcano in the city of Bronte. We use both nuts quite a lot both in savory and sweet recipes but while almonds are more assertive, pistachios are quite subtle in taste (and more expensive too).
Almonds are omnipresent in my pesto sauces but I have not worked extensively with pistachios before; I have then decided that it was due time to face the nut.
In this post, you will find a series of experiments I made with them, mostly savory with a great classic as sweet. Let me know what you think of them.
