Mentioned by The King on Tv4

And by king, I don't mean King Carl XVI Gustaf, but Norbert Lang, the king of truffles. Norbert loves life, he is a chef and a friend of ours who returns to our restaurant at home from time to time.

Here he teaches TV4 viewers the difference between real and fake truffles, and makes Jersusalem artichoke soup, body cakes and risoni with Gotland black truffle, also known as Gotland black diamond. He also mentions davidathome (at the end of the clip) to our delight.
