Tips
If your fillet is thinner at one end, you can neatly fold the end under itself to form an even thickness, then tie kitchen string along the fillet at 3cm intervals to keep it neat.
When cooking to the desired doneness, it is best to probe the meat with a thermometer. Check our cooking conversion times for an indication of desired doneness, temperature and cook time.
The meat continues to cook after removing from the heat. For example, the internal temperature (56-58◦C) so it can raise to 62-65◦C after resting for medium rare.
