Phil,
If you want to enjoy roo, the best way is to buy a fillet, slice it into thin steaks 1/4 inch thick, marinate in red wine and garlic, throw it on a hot BBQ, count 1000, 2000, 3000, 4000, 5000 turn it over, count the same again take it off and enjoy
Ps you can marinate it overnight and it still tastes great
