Any tender steak tastes terrific with traditional teriyaki marinade.
At this recipe we recommend Porterhouse, however you won't make a mistake with sirloin or even T-bone. The T-bone comes from the middle part of the short loin, between the Porterhouse and the club steak and even though it has a smaller fillet, is similar in texture and taste to the Porterhouse.
If you would like to grill these fine steaks without marinating it first, please do (use the marinade on round steak or rib steak). Rib steaks are less tender and fattier than club steaks, which they resemble in appearance.
Round steaks are from the rump and are quite lean, which is the reason they actually do very well when marinated - the less fat means the meat is drier compared to other pieces therefore advantages from a great soaking in a flavourful liquid.
