molecular dessert at Tickets restaurant in Barcelona. This dish is the signature dish of olive oil egg yolk created by Ferran Adrià while working in the famous bulldog restaurant. A translucent egg-yellow food, covered with a layer of transparent glue. After a bite, I was shocked that my mouth was filled with the aroma of olive oil instantly-this "egg yolk" was actually wrapped in olive oil. Although this idea has been copied into different versions by various fancy restaurants, the original version of this one will still leave a deep impression on people.
