Step 1
To begin, make the walnut purée. Drain the walnuts (reserving a little pickling liquid) and place in a food processor. Blend on high, slowly adding some of the pickling liquid to form a thick, smooth purée. Pass through a fine sieve and transfer to a clean bowl
Step 2
To prepare the salad leaves, cut the base from the chicory and remove any damaged leaves. Separate the leaves and trim the ends
Step 3
Trim the outside of the fris?©e lettuce and pick some nice pieces from the heart
Step 4
To cook the steaks, season with salt and pepper, pressing firmly into each side
Step 5
Place a pan over a medium heat, add the oil and butter and cook until the butter is foaming and smells nutty, but is not burnt
Step 6
Increase the heat and lay the steaks in the foaming butter. Cook for 2 minutes on each side, then remove from the pan and leave to rest in a warm place
Step 7
To serve, add the chicory, fris?©e, blue cheese, chives and pickled walnuts to a bowl. Season with salt and black pepper and dress with a little walnut oil
Step 8
Add a spoonful of the picked walnut purée to each plate and place a steak on top. Dress with the salad and serve.
