This is a simple tart that's flavored with blueberry and violet. Candied violet and fresh blueberries serve as decoration for the top of the tart. Violet also appears in the blueberry jam. Like with many of the more traditional pastries Frank Haasnoot does, the beauty of this tart lies in its simplicity, which comes from adhering to those qualities that make it an enduring classic in the first place.
