Ostrich is red meat much more like beef in taste and texture. Ostrich can be substituted for most any meat and grills very much like lean beef. As it is very lean meat, it can be tough if cooked too long. Because it is so lean you will see a lot less shrinkage during cooking and you won't have to drain away fat after cooking ostrich. You can fry or grill ostrich steaks as you would beef. Be sure not to overcook Ostrich.
