To prep, rinse the cranberries and dry them completely. Line a baking tray with parchment paper and set it aside.
Next, add ½ cup sugar and ½ cup water to a saucepan. Stir and cook over low heat until the sugar dissolves completely and the syrup starts bubbling.
Remove the syrup from the heat and add in the cranberries. Stir them for about 1 minute with the syrup until coated. Make sure not to keep them in too long or they may burst open!
Use a slotted spoon to transfer the syrup-coated cranberries to the parchment-lined tray. Try to separate them as much as possible so they don't stick together. Then, let dry for about 1 hour.
Add the remaining ¾ cup of sugar to a large bowl or container. Roll the cranberries in the bowl of sugar, a few at a time, until coated.
Transfer the sugar-coated cranberries to a bowl of plate to continue drying. Then, enjoy!
