This one is a simple one that can become kind of taste buds shaker. At the end it makes sense. Wash the arugula. For the dressing (photo): On a medium heat, warm the honey until it starts to caramelize. Add the vinegar,the shot of espresso, and the chocolate cut into small pieces. Stir well til the chocolate melt. Now there is two options to season the dressing. Either you have some meat demi glace that you add and let melt or if you want to keep it vegetarian add some soy sauce (the soy sauce will make it taste kind of meaty). Both will salt the dressing. Let cook slowly for 5 minutes,taste and adjust seasoning. In a bowl put the arugula, drizzle with dressing and sprinkle either or both pop corn and corn flakes. You can stop here and have a good time.
The deal its to find the balance between the bitterness of the arugula and the sweetness/boldness of the dressing.
