The Rock Sirloin is a temporary item in Majora's Mask. It can be obtained by venturing to the Goron Shrine, where Link finds multiple torches that aren't lit. He must light all the braziers on fire in order to turn the chandelier. Only when that is done and the chandelier begins spinning and several jars and pots will fall to the ground. The Rock Sirloin can be found in one of these, where Link must use the Goron Mask to turn into Goron Link to carry the Rock Sirloin to the Cold Goron.
