Fresh cranberries OR frozen cranberries I have a recipe that calls for 1 1/2 cup of fresh cranberries mixed with 1 cup of sugar (let stand). Then you add egg whites, orange juice and vanilla. Finally, you fold with whipped cream. 

Since cranberries are seasonal (and out of season right now) can I use frozen berries in this recipe and have the same results?
Yes, cranberries freeze extremely well.

Since you will be macerating them with sugar, and since the texture of fresh cranberries is not that pleasant anyway, any slight softening from the freezing should not be a detriment--it might even be an improvement.
