Lovers' salad

1. First make the dressing: whisk the egg yolk, mustard and lemon juice in a small bowl, then add the oil slowly, in a very thin stream (rather like making a mayonnaise, although the texture should not be quite so thick). Add the lemon zest, rosemary and a little seasoning. Chill and allow to steep for a few hours.

2. Just before serving, combine the salad ingredients and toss with the dressing. The flowers should be added last for visual effect: they can be added after the salad has been dressed, so as not to become wet. The whole meal is designed to be light but full of flavour.
