Cooking with sous vide is all the rage. Disciples of the method claim it's the best way to get a steak just right: Cook it to a precise temperature, then sear it off in a pan or on the grill. Perfection every time. For anyone who doesn't have a sous vide, there is another way with a more common kitchen appliance.
A standard dishwasher will do the trick, according to this video. Make sure your steak is vacuum-sealed and toss it in for a 90-minute wash (the temperature should be set to 122 degrees Fahrenheit; if you can't control the temperature, maybe it's time to get a new dishwasher). When it's done, finish it off in a pan with some olive oil and butter, and you'll have a nice medium-rare cut of red meat.
