Rita, ours marinated for about 2.5 hours, and once cooked, it tasted lovely. We did find though that following your cooking times meant that the tuna was still *very* raw inside.. But maybe our steaks were a lot thicker too? Once we had put them back in the pan for a about 8 minutes longer they were done to perfection. Definitely a recipe to keep on hand when tuna is affordableâ€¦ and basting with the marinade meant that there was some semi reduced, semi sticky, flavoursome stuff in the bottom of the pan to go over it.. Tasty with the garlic pasta and salad that we made to go with it. Please see my rating system: a wonderful 4 stars. Thanks Rita!
