Mix together and heat in a saucepan for 15 minutes
1 can of Ocean Spray whole berry cranberry sauce
1/2 cup brown sugar
1/2 cup orange juice
Pour it over the roast and continue cooking, very loosely covered, for another hour or longer if a large roast. If using tenderloins that cook quickly, shorten cooking time and add berries at start.
If you want to use a crock pot, make sure it's a lean piece of meat and add everything at the start, or drain liquid after a few hours and then add hot berry mix. Meat can be sliced (whether oven or crock) and added back to the juices to saturate each slice for the last half hour for more flavor but not necessary.
Sauce can be spooned over rice, or thickened over mashed potatoes.
