In a medium saucepan, combine 1 cup of granulated sugar and 1 cup of water. Place over medium heat and bring to a gentle boil, stirring occasionally for 3-5 minutes until clear.
Once boiling, gently add the rinsed cranberries and stir to coat. Let them bask for about 10 minutes.
Mix together the ground cinnamon, ground nutmeg, vanilla extract, and salt in a small bowl.
After 10 minutes, remove from heat and stir in the spice mixture, coating the cranberries well.
Strain the cranberries using a fine-mesh sieve or colander to separate from the syrup.
Spread the cranberries on a baking sheet lined with parchment paper and cool for about 15 minutes.
Toss the cranberries in the additional 1 cup of sugar until fully coated.
Allow the coated cranberries to sit on the parchment-lined baking sheet for about an hour to dry.
Transfer dried cranberries to an airtight container for storage.
