Our NEW times/temps chart! Sous vide cooking is a fool-proof way to bring a given food to its perfectly cooked temperature. But perfection, to a degree, lies in the taste of the beholder. One cook might consider the perfect medium-rare steak to be found at 134°F (56.5°C), while another’s might be a few degrees higher or lower. That’s the beauty of the precision of sous vide cooking! Once you have determined what perfection means to you, you can dial it in every time precisely to your liking.
