Cut the top and bottoms off of the citrus and then slice through one side, being careful not to cut into the fruit inside. Starting at the cut side, gently loosen the skin of the citrus in one large piece. Discard the fruit for another use. Slice the peel (no need to cut the pith off) into strips of desired thickness. 1/8-1/4 inch works well.
Add all the cut citrus peel to a medium pot and cover with water. Bring to a boil over medium heat and then discard the water. Repeat this process another 2 times. This will remove most of the bitterness of the pith.
After the third blanching, remove the citrus to a bowl and reserve. Add a cup of water, the allulose, monk fruit, and a pinch of salt to the now empty pot. Bring to a boil over low heat. When all the sweetener is dissolved, add the citrus. Cook uncovered on low for at least 1 hour, or until the liquid is thick and syrupy, stirring occasionally to rotate the citrus and ensure that the sweetener is not burning (high heat can burn allulose so be sure to cook on low).
When the syrup is thick and the fruit is translucent, add stevia to taste and then use a fork to transfer the citrus from the liquid onto a rimmed baking sheet lined with parchment or a silicon baking mat. Allow the peel to dry overnight and up to 24 hours.
Melt the chocolate (either slowly over a double boiler or in the microwave at 50% power, stirring every 30 seconds or so until liquid) in a glass bowl.
Dip the dried candied peel into chocolate and place back onto the prepared baking sheet. Let stand until the chocolate sets and then refrigerate until consuming.
