Peel the oranges and freeze or set aside for another recipe. Alternatively use orange peels you have saved previously.
Slice the orange peels into thin strips, and then set aside.
Bring a pot of water to a boil, and allow the orange peels to simmer for approximately 15 minutes. Drain and rinse with cold water.
Now in the same pot, bring equal parts water and sugar to a boil to make a simple syrup. Whisk until combine. Add the orange peels back in, and set to lower. Simmer on low for approximately 30 minutes, until the orange peels have candied.
Transfer to a parchment paper lined baking sheet, and allow to cool for 4 hours. You can store the candied citrus peel for up to a month in a cool, dry place on your countertop.
