Cranberry Butter

In a microwavable cup, combine the cranberries and the orange juice and bring just barely to a boil. Remove from the microwave and allow to soak & cool for at least 30 minutes. Drain the cranberries in a sieve and place them in food processor with the butter and sugar. Process until completely combined and fluffy.
Pack into small ramekins or roll into a tube in heavy plastic wrap. Refrigerate until needed, then remove from the refrigerator 15 minutes before serving.
