Was that the grassfed beef from Farmer Jacks. I got it B4 did it on the gasserand it was tough as... musta been run right across the Nullabor B4 it was killed here. But with the proper treatment and possibly some aging to help loosen the fibers it will be OK.
Farmer Jacks also has grass fed rib eye on special at the moment ... real ridiculously low price, below $10/kg.
Got to find work again first then will be ringing and coming over annoying you for some lessons and decent cookups.
