Roasted partridge, hay-baked celeriac, pearl barley and sprout leaves

To make the pearl barley, soak the barley in cold water overnight. Rinse under running water

Bring the water and chicken stock to the boil. Add the thyme, garlic, bacon and salt. Add the barley and cook slowly until tender. Season with salt, drain and cool spread out on a tray

To make the salt crust, heat the oven to 180˚C/Gas mark 4. Put the hay on a heavy tray and cook in the oven for about 6 minutes to blacken it. Allow to cool

Cut the hay into short lengths with scissors and mix with the flour, water and salt to form a dough. Roll out to a thickness of 5mm and cut out 1 or 2 discs depending on how many celeriac you have

To make the hay-baked celeriac, heat the oven to 220°C/Gas mark 7. Wrap the hay crust fully around each celeriac and bake them for 35 minutes

Reduce the heat after this time to 160˚C/Gas mark 3 and continue cooking for 25 minutes. Cool before cracking open the crust. Cut into 1cm slices and then cut out 4 x 2cm discs

Reduce the heat after this time to 160˚C/Gas mark 3 and continue cooking for 25 minutes. Cool before cracking. Cut into 1cm slices and then cut out 4 x 2cm discs

To make the partridge, prep the bird by first removing the legs. Remove the head from about ¾ of the way up from the body. Remove the neck and the membrane that is attached to the skin

Remove the wishbone. Make a slit between the top of the bird and the bottom so as to remove the guts, making sure everything is removed

Remove the bottom part of the carcass. Remove any remaining hairs from the bird. Seal each bird into a vac-pac bag with a 2 tablespoons of chicken stock. Chill until needed

Meanwhile, make the partridge sauce by browning the bones in some of the butter. Once coloured, drain in a colander. Retain ¼ of the bones to refresh the sauce at the end

Brown the onions, carrots and celery in the remaining butter until golden brown. Add the bay leaf, thyme and juniper. Drain and add to the bones

Boil the Monbazillac for 1 ¼ minutes. Reduce the Gewürztraminer to 35ml. Bring the stocks, Gewürztraminer and ¼ of the Monbazillac to the boil. Add the bones and simmer for 20 minutes

Pass through a fine sieve, put back in the pan and bring to boil. Reduce to a sauce consistency

Add the redcurrants, redcurrant jelly and the remaining bones, and bring back to the boil. Remove from the heat, taste and adjust with the remaining Monbazillac. Rest for 5 minutes then sieve

Once the sauce is completed, cook the partridge sous vide at 62˚C until the core temperature is 56˚C, which should take about 20 – 25 minutes

Rest for 8 – 10 minutes. Remove the partridge from the vac-pac bags, drain and fry in butter until browned all over

To make the garnish, heat 20g of butter in one pan and the rest in another. Add the sprout leaves to the first pan and the trompettes to the other. Sauté for 2-3 minutes or until cooked. Drain

Remove the partridge breast from the carcass, then trim and carve into equal slices, lengthways. Serve with the celeriac, sauce and garnish
