Cut grapefruit peel into long strips 1/4 inch wide.
Toss all of the peels into a pot with water to cover and boil. Drain water using colander. Repeat this process one more time. This helps to remove the bitterness from the peel.
Add grapefruit peels back to the pot with two cups of water. Then add the sugar and stir. Bring this mixture to a boil, then bring it to simmer for 35 minutes, or until the peels have become slightly translucent. The liquid will have evaporated down. Turn off the heat and allow to cool in mixture for 5 minutes.
Use tongs to move grapefruit peels to drying rack placed on top of baking sheet lined with parchment paper. Let the peels dry for 24 hours.
Save grapefruit simple syrup and store in glass container in fridge for future use.
After the peels have dried. Roll them on a plate or in a bowl with sugar.
Melt chocolate in microwave in 30 second intervals until the majority of the chocolate has melted.
Dip as much of the peel in the chocolate and set to dry on parchment paper.
