I Googled and found a recipe for it. Pork tenderloin, apples, cinnamon and brown sugar. Sounded good. The fact that there was no liquids concerned me. But I assumed that the pork would produce enough juice.
The pork was good but the apple combo stuck to the roasting pan and won't come off.
It's hard to clean.
So it will be soaking overnight.
Next time I'll include apple juice or water.
