Citrus peel, some cut with a peeler and some with a zester
Clear jars, (with tops) such as mason jars
Fill jars with sugar to a depth of 1/2-inch. Add some of the citrus peel then cover with another layer of sugar. Continue in this way, ending with the sugar about 1/4-inch from the top of the jar. Replace lid. Allow to sit for a few days so the citrus flavor infuses the sugar.
