Makes enough to sauce 2 tenderloins Immediately after placing pork in oven, add oil to still-hot skillet, swirl to coat, and set skillet over medium-high heat; add onion and cook, stirring frequently, until softened and browned about the edges, 5 to 7 minutes (if drippings are browning too quickly, add 2 tablespoons water and scrape up browned bits with wooden spoon). Set skillet aside off heat. While pork is resting, set skillet over medium-high heat and add port and cherries; simmer, scraping up browned bits with wooden spoon, until mixture is slightly thickened, 4 to 6 minutes. Add any accumulated pork juices and continue to simmer until thickened and reduced to about 1/3 cup, 2 to 4 minutes longer. Off heat, whisk in orange marmalade and butter, one piece at a time. Adjust seasonings with salt and pepper. Description: "This recipe works very well with pan-seared pork tenderloins."
