Fish stews are healthy, hearty and easy to make, needing only one pot. So it’s the ideal dish for a family meal on busy or lazy days. This potato and cod stew with green peas is a Middle-European dish, normally made with river fish such as trout or carp. If you don’t have peas, feel free to use green beans, broad beans, spinach or kale, as long as it’s a green vegetable. I normally use organic potatoes, as these don’t need to be peeled. If you want to speed up the cooking even more, make the potato stew ahead, chill or freeze it - then warm it up and add the peas and fish ( this only takes 10 minutes). Serve it with crusty bread and gherkins on the side.
