Slice cranberries in half and place in medium sized bowl. Zest entire orange and combine with cranberries. Add 4 Tablespoons Sugar in the Raw and toss to combine. Allow mixture to sit for at least one hour.
Preheat oven to 400 degrees F. Line a loaf pan with parchment paper or grease with butter or non-stick spray.
In a large bowl, mix together flour, sugar, baking soda, and salt. Set aside.
Juice orange into a measuring cup and then add enough water to equal one full cup (I had 1/2 cup orange juice and 1/2 cup water).
In a separate bowl, combine juice/water mixture with egg, melted butter, and vanilla. Add this mixture to the flour mixture and stir, just until combined.
Fold in cranberry mixture, reserving about 1/4 cup for the top of the loaf. Once combined, pour into prepared pan. Top with remaining cranberries, sugar and zest.
Place loaf pan in center of preheated oven and bake at 400 degrees for 15 minutes. Then, rotate pan and reduce temperature to 350 degrees F. Bake an additional 50-60 minutes until a toothpick inserted into the center comes out clean.
Cool loaf out of loaf pan on cooling rack until cool enough to handle.
