Genoese Minestrone with Pesto
Ligurian minestrone: a broth deepened with a Parmigiano rind, vegetables added in order of cooking time and a fresh basil pesto stirred in at the end.
Method
Prepare the vegetables. Finely dice the onion, carrot and celery (3–4 mm) and mince the garlic. Cut the potato and courgette into 1.5 cm cubes; top the green beans and cut them into 2 cm lengths. Rinse and drain the cannellini. Pick the basil leaves, wash them and pat completely dry with kitchen paper.
Heat the olive oil in a 20 cm pot, add the onion, carrot, celery and garlic and cook slowly over medium-low heat for . Keep going until the vegetables smell sweet, are very soft and just golden at the edges; this is what gives the broth its depth.

In a mortar, pound the garlic with the coarse salt to a paste, add the pine nuts and crush them, then add the basil a handful at a time, grinding with a circular motion into a deep green paste. Finally mix in both cheeses and stir in the olive oil in a thin stream. It takes about . If you use a blender, pulse in short bursts so the heat doesn't darken the basil.

Cook's tip
In Genoa this soup is often eaten lukewarm in summer. Walnuts work in place of pine nuts. Keep Parmigiano rinds in the freezer for soups; scrape off any wax or printing first. Leftover pesto covered with a layer of olive oil keeps for 3 days in the fridge.
Cooking it at camp
Make the pesto at home, pack it in a small jar topped with olive oil and keep it in the cooler. At camp you only cook the soup and spoon the pesto over each bowl. Pre-chopped vegetables in zip bags make it even easier.
