These tasty T-bone and Porterhouse steaks are from the Jan Zandbergen company in The Netherlands. They import quality meats from world wide Quality and this steak is from Brazil. The meat originates from the zebu variety of cattle.
Most of the T-bones are technically Porterhouse steaks because the tenderloin side of the steak is so large.
These steaks are cut to a farily consistent size, just under 500g or about 17 ounces.
