Is fresh always the best choice?

McClatchy Newspapers (MCT) - As summer wanes, value-conscious shoppers know a pint of fresh blueberries can wind up costing a pretty penny. A recent check of four local supermarkets produced wildly fluctuating prices _ anywhere from $2.88 to $4.99 a pint.

Looking for a bargain? Consider trolling the freezer case.

Cook's Illustrated found frozen blueberries were actually sweeter than fresh ones shipped long distances because they are picked at the peak of ripeness and individually quick frozen, known as IQF. If properly handled, frozen fruits and vegetables have the same nutritional benefits as fresh, the FDA reports.

The Star's Balsamic Glazed Pork Chops With Blueberry Wine Sauce combines fresh or frozen blueberries with red wine. Like blueberries, red wine is naturally high in resveratrol, a powerful antioxidant that may lower bad cholesterol, protect against heart disease and slow age-related memory loss.

Shopping tips: When buying frozen berries, check the bag to make sure there are no clumps, indicating the berries have thawed and refrozen.

A "dry" wine means all the sugar from the grapes has been converted to alcohol during the fermentation process. Typical dry red wines include Cabernet Sauvignon, Zinfandel, Pinot Noir and Merlot. But if you're looking for something more unusual, try Sangiovese, Malbec, Carmenere or Temperanillo. If you do not drink wine, substitute grape juice.
