Step by step
- Cut the Fenland celery into approx. 3 cm pieces, removing any tough ends or strings.
- Heat 1 tbsp of the oil in a frying pan and gently cook the Fenland celery and onion for 10 minutes, remove and add the bacon and cook until crispy.
- Cut 4 x 30cm circles of baking parchment, divide the Fenland celery and onion between the circles, then sprinkle over the herbs and bacon.
- Mix together the remaining olive oil, Dijon mustard and vinegar, this is best done in an empty lidded jam jar and giving it a good shake, divide between the Fenland celery parcels.

- Leave the parcels to cool for a few minutes before carefully opening.
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.
