White cranberry juice is made with young cranberries before they develop their tart flavor and red color—it's milder and sweeter than regular cranberry juice. Garnish with mint sprigs and whole fresh cranberries, if you like. Prepare the rosemary-infused juice mixture up to one day ahead, and chill.
If the cranberry mixture gets too thick, add a tablespoon of water and whirl it around in the food processor. You can also make this in an 8-inch springform pan; it'll be very full, so you should cook over a foil-lined baking sheet. Cook time will be the same.
In Melbourne, Florida, Betty Helton relies on a can of cranberry sauce to create the sweet sauce for this tender pork entree. She adds orange juice and ground cloves to the mixture to season it nicely as it simmers.
