You don’t always need a fruit salad dressing. The reason is that the natural fruit juices act as a sweet dressing. However, for this mixed berry salad, I wanted to add a fruit salad dressing. There aren't many natural juices that ooze out of the berries, so the maple lime dressing helps enhance the natural sweetness of the berries and adds juice. You will sometimes see honey lime dressing with berry salad recipes. That is also a great combination.
