Space Shuttle. The three Space Shuttle Main Engines, in conjunction with the Solid Rocket Boosters, provide the thrust to lift the Orbiter off the ground for the initial ascent. The main engines continue to operate for 8.5 minutes after launch, the duration of the Shuttle's powered flight.
Internal temp? I'm making http://www.food52.com/recipe... and it's a 9 pound pork shoulder that's been in the oven for 13 hours and has reached an internal temperature of 145. I've never cooked one before. Do I pull it out when the internal temperature reaches 160? Or does it need to continue cooking above that temperature to become meltingly tender?
As for how much to cook your pork, go by temperature, not color. The USDA recommends that pork be cooked to an internal temperature of at least 160 degrees, though chefs like Jonathan Zearfoss, culinary arts professor at the Culinary Institute of America, advocate for less. âFrom a purely aesthetic standpoint, I think 145 is well past the desirable temperature,â he says.
