Radicchio is quite a bitter leaf, so works well with sweet or creamy partners, as in this simple salad.
4 tbs extra-virgin olive oil
2 tbs red-wine vinegar
1 1/2 tsp sugar
Salt and ground pepper
1 head radicchio, shredded
1 pear, finely sliced
50g hazelnuts, almonds or walnuts, toasted and coarsely chopped
Optional: chopped spring onions
Optional: 70g sharp, salty cheese, such as goat's cheese or pecorino, chopped, crumbled or shaved
In a large bowl, whisk together oil, vinegar and sugar then season with salt and pepper. Add radicchio, pear and nuts (and onion, if using) and toss to combine. Scatter cheese (if using) over the top before serving.
