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.
During the last 15-20 minutes, regularly brush the glaze onto the ribs (e.g. every 4 or 5 minutes). Once cooked, remove from the grill and cover with foil. Leave in a warm place to rest for 10-15 minutes before serving. Chefâs tip: If the weather is too bad for a BBQ, you can cook the ribs in an oven instead.
