I always grab a few 'roasting beef' joints when they are going cheap from Lidl's or Morrisons (My local supermarkets), but as they are so lean I always cook them using my Texas wood mix (Oak, Pecan & Mesquite) at 150°C until the centre reads 50°C (I like it rare). Wrap & rest for 30 minutes in a warm place before serving. I rub the beef all over with olive oil first, then with a rub made from sea salt, lots of freshly ground mixed peppercorns (including some allspice), brown sugar & garlic powder & spritz every 30 minutes with a beer, worcester sauce & bourbon mix.
