Make the vinaigrette: In a small bowl whisk together the vinegar, syrup and shallot, add the oils in a stream, whisking, and whisk the vinaigrette until it is emulsified. Season the vinaigrette with salt and pepper.
Make the candied walnuts: In a saucepan simmer the walnuts in water to cover for 5 minutes, or until they are softened slightly, drain them, and transfer them to a paper towel to dry completely. In a bowl stir together the walnuts and the sugar. In a Dutch oven heat 3 inches of the oil to 350 degrees on a deep-fat thermometer and in it fry the walnuts in batches for 1 to 2 minutes, or until they are brown and crisp. Transfer the walnuts as they are fried with a slotted spoon to a baking sheet and season them with the salt and cayenne.
In a large bowl, toss the frisee with the dates and enough of the vinaigrette to just coat the salad, rserving any remaining vinaigrette for another use. Divide the salad among 6 plates, mounding it in the center, divide the cheeses and the bread around it, and sprinkle the salads with the walnuts and the herbs.
