First + foremost, rinse your berries. Toss any that are dry or just look bad. Put them in a sauce pot with 3/4 cup sugar (or use one full cup if you like your cranberry sauce to be sweeter) + one cup orange juice. Mix well! Bring it to a good bubble and stir often. Your berries will start to open and pop, and it will thicken a bit as you go. Once most berries are popped, remove from heat. It will keep thickening as it cools!
