It's well-known that roastbeef is a national dish in Great Britain. It's a soft and savory meat with a low content of fat, perfect for the whole family. Roastbeef is one of the protagonists of the so-called "sunday roast", together with mashed potatoes and Yorkshire pudding and horseradish sauce. It's perfect both served hot and cold, that's why it's a good idea also eat it in summer maybe in a sandwich!
Tie your tenderloin and marinate it with coarse salt, rosemary and thyme. Seal your tenderloin in a saucepan, on a high heat, with a dash of olive oil. Four minutes per side will be enough. Don't worry if it looks a bit burned! Now, cut in in thin slices and serve it with a drizzle of balsamic vinegar or lemon juice.
