In a medium saucepan, combine 1 cup of sugar, 1 cup of fresh orange juice, and 1/2 cup of water over medium heat. Stir gently until the sugar fully dissolves, which should take about 3-5 minutes.

Once the sugar mixture is ready, add 4 cups of fresh cranberries, a pinch of salt, a cinnamon stick, and the peel of one orange into the saucepan. Stir everything together.

Bring the mixture to a gentle simmer, stirring frequently to prevent sticking. Cook for about 10-12 minutes, watching the cranberries as they pop and soften.

If you prefer a smoother sauce, continue cooking for an additional 2-3 minutes, stirring gently.

Remove the saucepan from heat and let the sauce cool in the pot for at least 30 minutes.

Transfer your cranberry sauce to an airtight container, seal it tightly, and refrigerate until ready to serve.
