Combine orange juice, 1 cup cranberries, sugar and jalapeno in a saucepan. Bring to a boil over high heat. Boil cranberry mixture until pepper is softened, about 10-15 minutes. Remove pan from heat and let mixture cool for 2 minutes.
Puree cranberry mixture in a food processor until smooth. Stir in water.
Return puree to pan and stir in ½ cup cranberries. Heat sauce over medium heat until whole berries begin to burst, about 5-10 minutes. Cover sauce in a container and chill until ready to serve. Stir in mint just before serving.
