The sous vide method yields results that are nearly impossible to achieve by traditional means. In the photo above, both of the tenderloins started at the same weight. The steak on the left was cooked in a pan to a core temperature of 52 Â°C / 126 Â°F, but more than 40% of the meat was overcooked. The other steak was cooked sous vide to the same temperature and then seared with a blowtorch to yield a juicier steak that is done to perfection from edge to edge. Similarly, beef short ribs braised at 58 Â°C / 136 Â°F for 72 hours are melt-in-your-mouth tender, yet pink and juicy.
These stoves typically have capacities from 12,000 to 22,000 BTUs. Commercial-grade stoves generally have six burners and often feature accessories such as griddle plates or burners for indoor grilling. Like conventional gas stoves, they can be adjusted down to about 1,000 BTUs.
You need to establish the correct number of BTUs per square foot for your house needed to either heat or cool it. The methods differ for heating and cooling and are described below. Many furnaces and air conditioners will be labeled BTU, but this is actually shorthand for BTU per hour (BTU/h). At a bare minimum, you can use a figure of 20 BTUs per hour per square foot and multiply this by the total square footage to be heated or cooled, but this does not take into account climate, the amount of insulation you have, or the way you live.
