yeah sear and roast was what I was thinking then I got a look at your marinade and spices.
don't know about a steak that thick with the asian flavors going on.
personally I'd sear it, roast it then go mushrooms and madera
on edit: you probably already know this but satays and the asian flavors work really well with thinly sliced beef skewered on a stick.
Out of all the bulletin boards in all of the world you had to walk into this one. Didn't ya.
