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.
Step 2. Place the ribs on the grill, directly over the flames. Grill for about 8 to 10 minutes on one side, then turn them over using barbecue tongs and grill the other side for another 8 to 10 minutes.Brush the ribs with a prepared barbecue sauce on both sides a few minutes before you take them off the grill.ontinue basting the ribs every 30 minutes or so. Cook for a total of 3 to 5 hours, including the first 90 minutes, until the ribs are extremely tender and just starting to fall apart. At that level of tenderness, the ribs should reach at least 170 F in temperature.
