- 2 garlic cloves, peeled
- 2 tbsp olive oil
- 300–400g/10½oz–14oz fillet of beef
- 2 large potatoes
- 75g/2½oz unsalted butter
For the vinaigrette
- 1 shallot, finely chopped
- 150ml/5fl oz red wine
- splash red wine vinegar
- glug olive oil
- 1 lemon, juice only
- pinch caster sugar
- 1 tsp finely chopped chives
For the hollandaise
- 6–8 large bone marrow
- 200g/7oz unsalted butter
- 3 free-range egg yolks
- 1 lemon, juice only
- 1 tbsp Dijon mustard
- salt and freshly ground black pepper
Method
-
Soak the bone marrow in cold water, in the fridge, for 24 hours. Drain and blend in a blender.
-
Put the beef consommé, red wine, bouquet garni and garlic in a large saucepan and bring to the boil.
-
Meanwhile, heat the oil in a frying pan over a medium heat and sear the beef all over. Lower it into the consommé stock and poach at a simmer for 5–8 minutes. Remove the beef from the pan and set aside to rest.
-
Parboil the potatoes, leave to cool and then thickly slice them. Melt the butter in a sauté pan over a medium heat. Add the potatoes and cook for 7–10 minutes, or until starting to colour on both sides.
-
To make the vinaigrette, put the shallot and wine in a saucepan over a medium heat. Bring to the boil and simmer until the liquid has reduced to a tablespoon.
-
Put the remaining vinaigrette ingredients in a bowl, then whisk in the wine reduction.
-
To make the hollandaise, heat a frying pan until hot, add the butter and cook until it turns a nut-brown colour. Set aside to cool to room temperature.
-
Put the egg yolks and lemon juice in a food processor and gradually add the browned butter, bone marrow and mustard. Season with salt and pepper.
-
To serve, dress the potatoes in the vinaigrette and scatter over a large serving platter. Slice the beef and place on top, with the hollandaise spooned over.
