I had this tasty soup starter for one of our meals while on vacation in Switzerland this summer. I talked with the waitress and chef and they told me steps and ingredients and I replicated it as best I could. This soup is a great way to use your garden harvest or farmer market buys.
I used Russets in this soup instead of my usual Yukon gold potatoes as they break down easier and make the soup even creamier. The bread I used was a 2 day old stale light rye bread. The chef added the bread for two reasons, to use up the bread and to thicken the soup. No waste here!
This is the first time I tried kohlrabi. I tried a bite of it raw and a bite of it cooked. It is no surprise that it has a cabbage flavor both ways being that is from the cabbage family. The name comes from the German Kohl ("cabbage") plus Rabi (Swiss German variant of "turnip") Kohlrabi is a very commonly eaten vegetable in German speaking countries. Make sure you should peel off the tough outermost layer of the bulb with a vegetable peeler before cutting in half to get the core out.
