Prepare caramel sauce. Set aside.
Melt butter in large cast-iron pan over medium low heat.
Sprinkle with coconut sugar.
Without touching or moving the pan, carefully set pear halves side-by-side, being careful to ensure placing the pear in the pan is a clean set, with no movement.
Continue to cook over medium heat with an even temperature control for 4-5 minutes, or until pears are light golden brown. Watch carefully, if the sugar gets too hot, (medium temp and up), they will unevenly brown and quickly over brown. Check doneness by carefully lifting the side of a pair with a fork. You may need to flip around for even browning in pan.
When ready, carefully remove with spatula, ensuring to scrape the entirely of the underside of the pear to lift out of pan. Flip over and place on plate to cool. Serve at room temperature, allowing a few minutes for the sugar to cool.
