First I admit without any shame, remorse, or minor scrapes to my pride, that I love ALTON BROWN. I am a food junkie and a Good Eats neophyte. I've done all in my power to take classes taught by Alton Brown and I love his science. If you don't know what I am talking about, go to a library and look him up and if you have cable (or know anyone with TiVo), have them or yourself watch GOOD EATS on the Food Network. And chances are, you'll be a dork just like me!
Center Cut Tenderloin Roast
(seriously the best roast I have ever had - and being LDS, I've had a lot)
1 1/2 teaspoons kosher salt
1 1/2 teaspoons freshly ground black pepper
1 teaspoon freshly ground cumin
1 to 1 1/4-pound tenderloin roast cut from the center of the whole tenderloin
1 teaspoon vegetable oil
Preheat the oven to 250 degrees F.
Combine kosher salt, black pepper, and cumin in a shallow dish.
Roll roast in seasonings, coating well.
Preheat a cast iron grill pan over high heat.
Once the pan is hot, brush the roast with the olive oil, and sear on all sides, approximately 8 to 10 minutes total cooking time.
Remove the roast to a plate, cover with aluminum foil, and allow to rest for 10 to 15 minutes. Place the roast back onto the grill pan, put in the oven and cook until it reaches an internal temperature of 135 degrees F, approximately 15 to 20 minutes.
Remove from the oven, wrap in foil, and allow to rest for 30 minutes before cutting.
(really the cooking usually takes considerably longer than this, so please use a meat thermometer)
NOTE: If you are willing to spend more time with this, here is the link to the episode transcript, not just the basic bare bones recipe.
in here he details how to choose the meet, cut it right, how to use your tools to the best of your and their abilities and so forth ... it is well worth the read and the struggle through transcripted humor - which can be very painful.
