I used my handheld immersion blender to make this, so it was easy. I didn't have Dijon so I omitted it, and instead of fresh basil I used this stuff I found at the store - it measures like fresh basil, but it comes in a tube that you keep refrigerated. The dressing turned out great - just tangy enough and very fresh. I used it on a salad with spring greens, strawberries, mandarin oranges and walnuts. It did make a lot of dressing, so hopefully it keeps well.
Very tasty and different dressing. The basil and raspberry vinegar gave it an assertive, fresh taste and we really liked it over a simple salad of mixed greens, toasted walnuts and shaved parmesan.
