Medallions of Pork Fillet with Onion Puree, Mustard Seed Jus, Duck Fat Potatoes and Black Pudding

Ingredients – Serves 4

400g Pork fillet

500ml Beef Stock

2 Large white onions, roughly chopped

300ml Jus (rich gravy)

25g Mustard seeds

3 Large Agria potatoes

500g Duck fat

200g Black pudding




  • 1. Preferably the day before trim the fat from the pork and roll in glad wrap to form sausage shapes.
  • 2. If you’re making the jus yourself then you can also do this the day before. You can do this by roasting beef bones then boiling them in water with carrots, celery, leek, garlic, bay leaves, peppercorns and onions to make a dark beef stock. You then discard the vegetables and bones and reduce the liquid with red wine. When you have a rich dark gravy then it is ready. In the restaurant we get approximately 3 litres from a 20 litre stock pot so you have to reduce this quite a bit.
  • 3. From here you have a base jus for which you can make any flavour you like, for this recipe simply add mustard seeds to your jus and simmer for 5 minutes to soften the mustard seeds.
  • 4. For the onion puree: Combine salt and pepper with the peeled and chopped onions and beef stock then reduce until you only have approximately 100ml of liquid. Puree and set aside.
  • 5. For the potatoes: You can cut these to the shape you like, I use a Parisienne scoop and shape like melon balls. In a deep tray melt the duck fat until it is all liquid. Add the potatoes and put them in a hot oven uncovered until they are golden brown and crispy (approximately   30 minutes). You can time this to serve immediately or re-heat them later in a hot oven.
  • 6. Your pork that you rolled should now be cut into medallions ready for pan frying. Simply slice into 2 inch pieces and then remove the glad wrap. Do the same for the black pudding as well. In a pan add oil and heat then add your medallions and black pudding so they sizzle. Cook on all sides until they are golden brown and the black pudding is crispy. The pork can be slightly pink if you don’t mind this.
