@merpreb @lioness I cooked a tenderloin roast for Christmas dinner and followed Ina Garten's recipe. It was 500° for about 30 minutes. My son, who cooks a bit, thought it was going to turn to ash but it was perfect! When we were visiting him in February and his future parents-in-law came too, he cooked one also, following the same recipe. Perfect. It is alarming, but dear Ina, knows her stuff.
