Under the conditions of metamorphism the calcite in the limestone recrystallizes to form a rock that is a mass of interlocking calcite crystals. A related rock, dolomitic marble, is produced when dolostone is subjected to heat and pressure.

1 Smoke the ribs at 225Â°F to 250Â°F for four to five hours. 2  You can baste or mop the ribs occasionally if you like, but donât open the grill too often. 3  Maintaining a steady temperature is the most important thing.
Place the ribs on the grill over direct medium heat and cook for 1 hour, with the lid closed, occasionally turning the packets over for even cooking, making sure not to pierce the foil. Remove the packets from the grill and let rest for about 10 minutes.
