The day before serving, make the parsley oil. Blanch the parsley in salted boiling water for 1 minute. Drain, transfer to a liquidiser and blend with the oil until smooth and bright green

1 bunch of flat-leaf parsley
500ml of grapeseed oil

Transfer to a cheesecloth and hang overnight in the fridge with a jug positioned underneath to collect the oil. Store in a bottle until needed

To prepare the beef, mix together all of the brine ingredients in a large pan and bring to the boil. Once boiling, remove from the heat and chill immediately

200g of sea salt
1l water
200g of soft brown sugar
20g of black peppercorns
20g of coriander seeds
15g of fresh thyme

Once chilled, add the sirloin to the brine and set aside for 2 hours

1 sirloin of beef, weighing 3.5-4kg

Preheat a water bath to 52˚C

After this time, remove the beef from the brine and rinse under cold water. Add to a vacuum bag with the beef dripping and seal in a chamber sealer. Cook in the water bath for 2 hours

50g of beef dripping, rendered

While the beef is in the water bath, prepare the other dish elements. To make the beer and beef sauce, place a large pan over a high heat and add the beef dripping. Once melted, add the beef trimmings and cook until nicely browned off

500g of beef trimmings
20g of beef dripping

Remove the trimmings from the pan but retain the fat. Add the shallots, garlic and peppercorns to the fat and slowly caramelise. Once golden, add the vinegar and deglaze the pan

10 black peppercorns
8 shallots, sliced
1 bulb of garlic
25ml of sherry vinegar

Add 700ml of the beer to the pan, reduce by half, then add the red wine and reduce again by half

500ml of red wine
700ml of beer, dark

Return the trimmings to the pan, add the thyme and cover with the beef stock. Cook the sauce for 25 minutes, skimming the fat away from the surface as it reduces

10g of thyme
3l beef stock

Pass the sauce through a fine sieve and reduce to the desired consistency. Set aside until ready to serve

To make the parsley root purée, melt the butter in a pan and add the parsley root. Sweat with no colour for 20 minutes, or until soft

250g of parsley root, peeled and finely diced

Add the cream to the pan, transfer everything to a liquidiser and blend until smooth. Season to taste then adjust the consistency with a little vegetable stock

To make the salted caramel onions, cut each onion in half lengthways but leave the skins on. Heat a heavy-based pan over a medium heat, add the butter and sugar and allow to melt

100g of caster sugar
5 onions
100g of butter

Once melted, scatter over some salt and the thyme leaves. Place the onions in the pan, cut-side down, and allow the butter and sugar to caramelise – the onions will start to colour nicely

1 sprig of thyme, leaves picked

Once the onions are a dark golden colour, season with pepper, cover the pan with foil and finish cooking in the oven for 20 minutes

Remove from the oven and carefully remove the skins and first layer from each onion half (reserve the pan with the caramel in for reheating and glazing the onions later). Discard the skins and keep the outer layer to drizzle some sauce in when serving

When the beef is ready, remove from the bags and dust the flesh with icing sugar, without sugaring the fat

icing sugar, for dusting

Place a large pan over a high heat and once hot, add the beef. Caramelise the flesh until very dark in colour and the sugar almost burns. Once the flesh is blackened, place the beef fat-side down and gently caramelise the fat until it's a lovely golden colour

Remove the beef from the pan and allow to rest for 10 minutes before serving
