A savory, slightly sweet sauce with a hint of apple flavor provides a nice accent for the tender, flour-crusted pork and glazed mushrooms. Serve this with orzo, rice, risotto, polenta or mashed potatoes.
Measure the frozen apple juice concentrate and let it thaw. Clean whole mushrooms one at a time with a damp paper towel. If needed, rinse them lightly and dry with paper towels. Slice the mushrooms and set them aside.
Peel and mince the garlic and set it aside. In a dinner plate, combine the flour with ½ teaspoon salt and ¼ teaspoon pepper. Set the flour mixture aside.
On your largest cutting board, trim the silver lining of fat from the pork using a large knife. Discard the fat and slice the pork into medallions about ½-inch thick. Spread out the pork slices in a single layer on the cutting board and lightly cover them with plastic wrap to prevent a mess when pounding. Pound the meat to ¼-inch thickness using a mallet or heavy-bottomed pan.
Discard the wrap and set up an assembly line from left to right with the pounded meat, the flour, and an empty platter or sheet pan. Using a fork, dredge the pork in the flour, coating each slice on both sides and using the back of the fork to pat the flour into the meat. Place the floured pork onto the platter or pan as you go. If you have to stack the meat, you may want to use wax paper to separate the layers, to prevent sticking. Discard any remaining flour mixture.
Heat 1 tablespoon olive oil in your largest skillet over medium-high heat. Add the pork in a single layer (you will need to do this in batches) and brown it for around 3-4 minutes on the first side, then 2 minutes on the second side. Remove the partially cooked meat to a clean platter; stacking is fine. Cover with foil to keep warm. Continue browning the rest of the meat, adding another tablespoon of olive oil to the pan if needed. Remove the pork and keep warm.
Add butter to the pan and when it melts, add the garlic, stirring. After 30 seconds, add the mushroom slices, ¼ teaspoon salt, ¼ teaspoon pepper and stir to coat. Cook and stir for five minutes.
Add the apple juice concentrate and all of the pork to the pan. Stir it once to coat the pork with the juice. Cover the pan and simmer on low for at least 15 minutes. Check for doneness by cutting into a piece of pork. It should no longer be pink inside. Taste for seasonings, and add red pepper flakes if desired.
Store leftovers in the refrigerator for up to four days.
Purchasing sliced mushrooms may seem like a time saver but will take longer to clean if they have lots of dirt. I've learned the hard way to buy whole mushrooms.
If making this for company, you can cook this ahead of time and keep it covered in the pan, off the heat, for up to 1 ½ hours, then reheat it in the pan before serving (otherwise, store it in the refrigerator.) Leftovers do well in the microwave.
This recipe makes a lot of food, but people will take second or third helpings, and leftovers are even better the next day. Feel free to halve the recipe, if needed.
