On a whim, I bought a box of salt cod (an unusual ingredient in the UK), which hung around in my fridge for a few weeks, reproaching me. Finally I plucked up the courage to cook it, and soaked the cod for the requisite 24 hours. However, I forgot to look for suitable recipes for it, so when it was suddenly time to cook our evening meal, I trawled the contents of my kitchen, throwing things randomly into the saucepan, and concocted this dish - which was surprisingly successful, and which I will definitely be making again. It is a fresh-tasty summery stew of salt cod (also known as saltfish, bacalhau, bacalao, morue or baccalà) with tomatoes and courgettes (zucchini). Serve with mashed potatoes or polenta. Warning - make sure you soak your cod well, or this dish may turn out too salty, with no easy means of remedying the problem! Most of the preparation time is the soaking time for the cod.
