If you choose to try the baking soda bath, see instructions above.
Salt both sides of pork chop gently with salt. Both the miso and the tamari are salty so err on the side of moderate, but meat needs a lot of salt to get the full extent of flavor. The biggest mistake home-chefs (like me!) make is not using enough salt.
Cover each chop with a generous amount of soy sauce. Flip them back and forth so salt and soy blend.
Add onion powder and garlic granules and do the same.
Drop the miso on top of each chop and spread evenly.
Add the pistachios to one side of the chop and press gently so they adhere into the chop.
Cover and let the chops marinate for 2 to 8 hours in the refrigerator.
Bring to room temperature before cooking.
Spray grill with cooking oil. Heat grill to high and cook chops for 6 minutes on un-nutted side, turning to get cross-hatch pattern. So, 3 minutes--turn--and 3 minutes turn again t get that cross hatch pattern
Flip the chops onto a sheet of oiled foil and cook another 8-10 minutes or until chops register 140 degrees on a food thermometer. The cook-time depends greatly on the size and thickness of your chop. That is why I like the food thermometer.
