SERVES 4

The versatile sauce used here comes from Rogers Gray Italian Country Cook Book (Random House, 1995), by Ruth Rogers and Rose Gray, chef-owners of London's acclaimed (and very Italian) River Café. It can be used not only as a dip for radicchio and other vegetables, but also spooned over grilled or roasted fish or lamb. Rogers and Gray recommend green Tuscan olive oil.

2 tbsp. fresh young rosemary leaves
12 anchovy filets
Juice of 1 lemon
2/3 cup fruity extra-virgin olive oil
4 heads treviso or 2 heads chioggia radicchio
   (or a combination of both)

1. Place rosemary leaves in a mortar and grind as finely as possible. Add anchovy filets and grind to a paste. Add lemon juice, mix well, and then, stirring constantly, add oil, a few drops at a time. Transfer sauce to a small bowl.

2. Core treviso or chioggia radicchio. Separate leaves and arrange them on a platter around sauce.
