This fantastic salad is made of fennel, radish and pear sliced with a mandolin, see picture in the recipe below.
If you don’t have a mandolin like that, you could slice the fennel and radish very thinly with a sharp knife. The pear is easier to get slice without a mandolin. I recommend a mandolin though, so you’re better off buying one. They are not expensive, and it’ll save you a lot of time. I often use such one for salads.
The characteristic of this salad is the very thin slices that will soften in the dressing, which makes the salad smooth and soft. You can make the salad a day before serving and save leftovers as well. The choice of vinegar or balsamico will change the colour of the salad, which is why my salad turned out darker. I use an aged balsamico.
