Kobe is a prized Japanese beef is known for its rich texture, exquisite marbling and price tag. It's also not possible to procure outside of Japan, due to the country's strict exportation laws. However, Wagyu -- the breed of Japanese cattle that Kobe comes from -- has been imported to the United States, and ranchers here are producing their own version of the premium beef, complete with high prices.
Savvy cooks can get around the price tag by substituting USDA Prime beef. If that's still too pricy (most prime cuts are given to hotels and restaurants, and it can be expensive), pick up a choice-graded cut of beef from your local supermarket. Look for a cut with lots of marbling, as that's what gives the meat its desired texture.
