* 4 150g fillet Steaks
* 50g Unsalted butter, softened
* Good quality Balsamic vinegar
'''to serve'''
* Watercress to serve


===Method===
* Prepare the Butter at least a couple of hours before you are going to serve your Steak.
* Mash the Butter and Balsamic vinegar together until well combined. You will probably need a couple of tablespoons of Vinegar; it should end up a chestnut colour.
* Roll into a Fat Sausage shape and wrap in Cling film. Store in the Fridge until set hard.
* Season your steaks on both sides with Salt and Pepper. Heat a ridged Grill pan until very hot and sear steaks for a few minutes on each side until cooked to your liking. Rest for a couple of minutes (remember they will continue to cook during this process) and serve with a slice of Butter on top and some Watercress on the side.
