Just a few months after Tatarî accepted his new employment as the imperial art collector, he began secretly traveling to
Basel. Between March and September 1861 he visited the city thirteen times, coming every other weekend with only two disruptions to this schedule, and lodged in the Hotel Gasthof zum
Wilden Mann. During his stays in Basel, he developed a
chocolate recipe that is a
fusion of
Turkish coffee and Swiss
absinthe. For the production of the chocolate, he used South American
cocoa beans that were brought from the
Suchard factory in
Neuchâtel by his friend
Louis-Daniel Perrier. In his letter to Perrier, which is found in a private archive in Neuchâtel, he talks on a great deal about the content of the recipe and describes the way his chocolate should be consumed, but does not reveal the exact recipe. He also says that he sealed his recipe inside a tiny glass tube, placed it in a wooden looking metal crate, and threw it in the waters of the
Rhine: Whence you consume the chocolate, you should be viewing art; art of any kind I say, art that would normally provoke you, but somehow cannot. You will feel a transformation in the level of your perception, it will transform you into a connoisseur of art, and you will appreciate life through enjoying and understanding art, in your heart, and in your mind. […] It will be this chocolate to enable me, you, and all the others, to reach over, and individually grasp the idea that lies beyond the world of semblances. Today this chocolate is being produced by a Basel based chocolate company, Beschle Chocolatier Suisse, with the brand ‘The Lore of Tatarî Oğuz Effendi', and it can be purchased in single
truffle packages. In March 2011, exactly 150 years after the event occurred in the city, the veracity of the events has been acknowledged by
Basel-City with a commemorative plaque, which points out the resting place of the recipe. It reads: On 22 September 1861 Tatarî Oğuz Effendi (1831-1871) threw the recipe of his occult chocolate in a metal crate to the Rhein. It is believed that the crate is located under the main abutment of the Mittlere Rheinbrücke today. ==Later years in Paris==
