Recipe:
Beef rump cap, mine was 3,3 lbs/1,5 kg
4-5 medium onions
1 tablespoon salt flakes or whatever salt you have
1 tablespoon peppercorns
1,5 tablespoons olive oil
1,5 tablespoons soya sauce
1 tablespoon Worcestershire sauce
1 tablespoon Dijon mustard
Half a teaspoon sugar
Half a teaspoon Cayenne pepper, or a little more if you like it more spicy
1 teaspoon Cajun spice mix
1 teaspoon dried rosemary
1,5 tablespoon/20g butter
Half a cup/115ml chicken stock or beef
Fresh thyme

Cook the meat in preheated oven 212F/100C, no fan and stick a thermometer in the thick part after an hour. Mine was ready in about hour and a half, so that was like half an hour per pound/0,5kg.
Mine internal temp was set on 137F/58C. If you want it more red set it to 131F/55C, for less red set it 140F/60C.
