Step by step
- Preheat oven 200c/ 180c fan/ gas 7. Grease a shallow roasting tray or heatproof baking dish large enough to hold the fish fillets and tomatoes on the vine.
- Mix together the breadcrumbs, Fenland celery, zest of the lemon, parsley, chopped walnuts and olives. Stir in 1 tbsp of the olive oil and a good squeeze of lemon juice, season to taste.
- Pat the cod fillets dry with kitchen paper, place on the baking tray and spread evenly with the crème fraiche then top generously with the breadcrumb mixture, pressing down lightly to ensure a good coating. Add the cherry tomatoes to the tray and sprinkle with the remaining olive oil.
- Cook in the oven for approx. 15 minutes until the fish is cooked through and the topping golden.
- Serve with a squeeze of lemon juice and some new potatoes.
Cook’s tip: Fenland celery is a heritage variety of celery grown in the Cambridgeshire Fens. In 2013, Fenland celery was awarded Protected Geographical Indication (PGI) status and joined the ranks of Parma ham, Champagne and Melton Mowbray Pork Pies. Fenland celery is only grown in small pockets of Cambridgeshire, Suffolk and Norfolk using traditional farming methods. The deep, peaty soils in the Fens work towards giving Fenland celery its nutty-sweet flavour and paler colour. Fenland celery is available from October to December and can be found in Waitrose, Ocado, Wholefoods and Marks & Spencer.
