2) Fill a bowl with water and squeeze a little lemon juice into the bowl. Slice the artichokes thinly and immediately put them in the lemon water. Slice the taleggio into sticks about 4cm long by 0.5cm wide.
3) In a blender, puree the grapes, olive oil and verjus. Season lightly with salt and pepper. In a large bowl, combine the frisee, drained artichokes (pat them dry with kitchen paper), and the cheese. Season with salt and pepper and toss with 120ml of the grape puree.
4) To serve, mound the salad in the centre of a plate, top with a few langoustines and drizzle extra dressing over the top. Finish with freshly ground pepper. Serve immediately.
