I'm always futzing with my tuna-cooking technique in our family-favorite recipe of Seared Tuna with Ginger-Shiitake Cream Sauce. The recipe for the sauce is pretty much perfect as written (except I make a double-batch of sauce for 6 servings... because it's that good and I always want guests to get as much as they want...), but the prescribed method of cooking the tuna is kind of stupid. After playing around with a few methods, I have finally found The One, giving me just a couple millimeters of sear on the outside with an interior that is warm and bright pink all the way through.
The key to this technique was to partially freeze the tuna steaks (for about 30-60 minutes... we just threw them in the freezer while we enjoyed a pre-dinner cocktail on the patio) before searing in a very hot pan. (This prevents the interior from overcooking while you get a good sear.) From here you chill again for a few minutes before vacuum sealing and throwing into a 110°F water bath for 30 minutes. This is the only way I'll be doing my tuna steaks from now on... Perfection!
