CHARGRILLED SIRLOIN WITH MASH AND SALSA VERDE

Steps:

• To make the mashed potato, put the potato in a saucepan and cover with cold water. Add salt, if desired, and bring to a boil. Cover and simmer for 20-25 minutes, or until tender. Drain and return the potato to the saucepan. Put the saucepan back over low heat and let the pan and the potato dry for 1 minute. Remove from the heat and mash the potatoes with a potato masher. Add the butter and pepper. Return to low heat. Stirring vigorously with a wooden spoon, gradually add the hot cream (or as much as necessary) until the mixture is light and fluffy.
• While the potatoes are cooking, make the salsa verde. Mix together all the ingredients in a food processor and blend to a paste.
• Chargrill the sirloins. Make sure the fire has burnt down to very hot embers or turn on the gas barbecue. Rub olive oil and pepper over the steaks. Place on a grill over the fire and cook for about 8-10 minutes on both sides, for a rare steak. Remove to a warm place and allow to rest for 15 minutes.
• To serve, place the steak on warm plates and spoon the hot mashed potato next to it. Pour the heated demi-glace over the steak and top with the salsa verde.
