The day before you want to cook the venison, place it in a tub only slightly larger than the joint itself along with the wine, vinegar and olive oil. Lightly crush the spices, tie the herbs with some string and add those too. Make sure the venison is covered – or mostly covered – by the wine mixture then cover and refrigerate. Turn the meat once or twice if it is not completely submerged.

Next day, take the tub out of the fridge a few hours before you want to cook the meat, so it can come up to room temperature. Preheat your oven to 225°C. Calculate your cooking time: for rare meat roast for 15 mins per 500 g of meat plus 15 minutes; for medium 18 mins per 500 g plus 15 minutes.

Now prepare the meat. Spread your vegetables in the centre of the tray and place the venison on top. Dab it dry with some kitchen paper then smear the top with the butter, season well with salt and pepper, then cover the top with the bacon, making sure each rasher overlaps the next slightly.

Ladle around half of the marinade into the tin and slide the meat into the oven. Roast for 15 minutes and then turn the heat down to 180°C. Baste the venison every 15 to 20 minutes or so, adding more marinade if it starts to dry up.

For the last 15 minutes of the cooking time, turn the heat back up to 225°C, remove the bacon, give the meat one more baste, and let it crisp up at the edges. Take the tin out, remove the meat to a board or dish and cover with kitchen foil. It will sit very happily there as you roast your potatoes and cook your veg.

Now make the gravy. Strain the contents of the tin into a jug and spoon or pour a couple of tablespoons (approximately) of the buttery olive oil layer into a saucepan. Discard the rest of the fat. Put the pan over a medium heat and stir in 2 teaspoons of cornflour. Once incorporated, cook for a minute before adding the juices. Mix to blend, before adding the beef stock, mix again and then add the remaining marinade. Cook for 10 minutes, then add the jelly and season with salt and pepper. If the gravy isn’t as thick as you’d like, slake another teaspoon of cornflour in a little cold water and stir it in. When ready, strain into a warm jug.

Remove the outer mesh covering the joint, slice and serve with the gravy, the crisp bacon rashers and extra jelly on the side.
