This post comes from the diary of my trip to Austria, where I stayed with Imogen and Günther, who grow walnuts. Walnuts are one of the best nuts I know, and I was surprised to see that Imogen and Günther also have a tree (not commercial) of red walnuts. I have never seen red walnuts before, the shells are normal brown, but the kernels really red! Our hosts gave us some red walnuts, but also some walnut oil. In the photo above you can see the walnut plantation (only one tree produces the red walnuts).
For an easy salad mix the walnuts with rocket, walnut oil, salt, and lemon juice. Quick, healthy and good looking!
I decided to also make a walnut pesto for pasta. Using a mortar and pestle (or food processor if you don't have a mortar and pestle) mush the walnuts (I used the red ones, but you can use normal walnuts) with a peeled garlic clove, then slowly add some walnut oil (or olive oil), and a little salt and pepper to taste.
