What is vysoký roštenec in New Zealand?

NZ dining defaults to Medium for grass-fed cuts like Sirloin and Rump because grass-fed beef toughens at higher temperatures more rapidly than grain-fed. Lower cooking temperatures (Medium-Rare to Medium) preserve juiciness in NZ beef. Eye Fillet is typically served Medium-Rare. Important note for US visitors: NZ grass-fed beef should be cooked at LOWER temperatures than equivalent USDA cuts to compensate for the leaner profile.
