Start by brewing coffee. You want it strong, but not too bitter as the bitterness will cause the chops to be bitter. Set aside 3/4 cup to be cooling while you whip up the marinade.
Why should you marinate? Four good reasons include enhancing the meat's flavor, keeping the meat moist and juicy, creating a beautiful, crisp crust on the meat, and improving overall health by reducing unhealthy HCAs (possible carcinogens created when meats are cooked at high temperatures). The next eight ingredients make up part of the marinade, so mix them together before adding the cooled coffee.
Next, and this is very important, do not use all of the marinade for the meat! You will be using a portion to make a glaze to put on right before serving, so don't use it all or you will have to make more. Simply remove 1/2 cup of the marinade and place it into a zip top bag. Then insert the pork chops, seal the bag and give it a good squish. Place in the fridge (I like to put it in a bowl or pan so that it doesn't move around too much) for at least two hours. If you can let it go overnight, the flavors get even richer. Place the remaining marinade-that-will-become-a-glaze in a covered container in the fridge until needed.
About twenty minutes before you put your pork chops on the grill, pull out your leftover marinade and place it in a saucepan. You want to cook this on medium heat until it reduces by half, roughly 10-15 minutes. Remove the thyme stems before using. Turn off or keep on low until ready to use.
When it's grilling time, preheat your grill to medium-high heat. Then use some oil-soaked paper towel to oil your grill a little. I find it helpful to grip the paper towel with tongs to avoid getting burned, setting things on fire and the like. You just don't want those pork chops getting stuck. Grill 3-4 minutes per side until they reach doneness and an internal temperature that you prefer. Typically, this is 145 degrees for medium rare and 160 degrees for medium. Then place the meat on a plate to rest for approximately five minutes before spooning the glaze over the chops.
If you would prefer to broil instead of grill these delicious chops, broil 4-5 inches from the heat source for 4-5 minutes per side.
