Use canola for high heat for a better sear. The fuck do you want to taste olives on your steak? Canola is neutral. If you want at the end put some butter on top.
Why? It's dark meat. Toss it to the dog/cat/foxes. That's all it's good for. That or stock maybe if I am honest. Spend a few extra pennies and get some breasts and have some dignity for Christ's sake.
