Braised Beef Ribs with Tarragon Emulsion, Celery Fondant and Pickled Port Wine Onions

Braised Beef Ribs

1. Preheat a water bath to 65°C.
2. Season the beef with liquid concentrate and sear in a hot pan, until Maillard reaction has taken place.
3. Place portions of the ribs in medium or large vacuum bags. Add the beef and veal stock and season with thyme and cracked black pepper. Vacuum seal on full pressure. Place in the water bath and cook for 48 Hours.
4. After the cooking time, remove the beef ribs from the bag. Prepare the sauce by draining the stock through a fine sieve into a pan and reduce by half. 
5. Finish the meat by re-searing.  Place on a tray and slice ready for serving.
6. Hot-hold the reduced sauce ready for service.  

Celeriac Fondant

1. Preheat a water bath to 83°C.
2. Cut the celeriac into slices approx. 2cm thick. Season and place in a sous-vide bag in a single layer with a few small cubes of butter. Seal under full pressure, place in the water bath and cook for 4 hours.
3. Remove and cool at room temperature for 15 minutes then place in ice water until thoroughly chilled.
4. Prepare before serving. Clarify the remaining butter and heat in a small sauté pan to very hot. Remove the celeriac from the sous vide bag, and brown in the pan on one side. Remove from the heat and pour off the butter. Add the chicken Stock to the pan and warm through, gently shaking to coat the fondant.
5. Cut to suitable size and hot-hold for service.

Tarragon Emulsion
