Choose Organic Fruit
Since most pesticide residue is found in the skin, it’s important to use organic fruit when making candied citrus peels. Most but not all organic citrus is unwaxed. If you can find only waxed organic citrus, use a vegetable scrubber or clean toothbrush to remove the coating. The sweetest citrus fruits—‘Meyer’ lemons, clementines, ‘Minneola’ tangelos, pomelos, honey tangerines—yield the sweetest candy, but grapefruit also works well.
