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?
Roast the pork at 500Â°F for the first 20 minutes. We start at a high temperature so that the outside of the roast will turn all brown and crispy and delicious. You might see a bit of smoke inside the oven, but that's OK â don't panic! After 20 minutes, lower the heat to 250Â°F and cook for another 2 hours or so.
