Mixed vegetable stew (Ciaudedda)

Shell the fresh fava beans and fresh peas.

Trim the artichokes by removing the tough outer leaves and thorny tips. Cut them into quarters and remove the fuzzy choke. Immediately place the trimmed artichokes in acidulated water (water with a squeeze of lemon juice) to prevent browning.

Peel the potatoes and cut them into 2cm cubes.
