To Serve
Method
Make the Watercress & Parsley Oil
- Blanch the watercress and parsley in salted boiling water for 1 minute.
- Drain thoroughly and squeeze out any excess water.
- Transfer to a blender, add the rapeseed oil, and blitz until smooth and bright green.
- Strain the oil through a fine sieve and store in a bottle in the fridge.
Preheat the Water Bath
- Set a sous vide water bath to 54°C.
- In a pestle and mortar, crush the lemon thyme, Maldon salt, and black pepper. Generously season both sides of the steaks.
Cook the Beef Sous Vide
- Place the seasoned steaks into vacuum bags and seal.
- Cook in the water bath for 1 hour.
Prepare the Beer & Beef Sauce
- While the beef is cooking, heat a pan over high heat. Add the rapeseed oil and beef trimmings, cooking until well browned.
- Add the shallots, garlic, and slowly caramelise until golden. Deglaze the pan with sherry vinegar.
- Pour in the IPA and reduce by half. Add the red wine and reduce by half again.
- Add the thyme and cover with beef stock. Simmer for 15-20 minutes, skimming off any fat as it reduces.
- Pass the sauce through a fine sieve and continue to reduce until it reaches the desired consistency.
Make the Parsnip Purée
- Melt the butter in a pan over low heat. Add the diced parsnip and sweat gently for 20 minutes, ensuring it does not brown.
- Add the double cream and blend until smooth. Season to taste. If needed, adjust the consistency with a little vegetable stock.
Make the Caramel Beer Onions
- Cut the shallots in half lengthways, keeping the skins on.
- Heat a frying pan over medium heat, then melt the butter and sugar together.
- Sprinkle over salt and the thyme leaves. Place the onions cut-side down and caramelise until deep golden brown.

Blacken the Beef
- Remove the beef from the vacuum bags and pat dry with a kitchen cloth.

Seal the Beef

- Remove from the pan and allow to rest for 10 minutes.
Fry the Parsnip Crisps
