Blueberries Print E-mail

Wild blueberries are smaller in size compared to their cultivated cousins. Blueberries have a protective light powdery coating on the skins and tend to last longer than other berry varieties. Nearly half of the cultivated blueberries grown are sold as fresh blueberries. Fresh blueberries are available for nearly eight months of the year from producers across the United States and Canada. North America is the world's leading blueberry producer, accounting for nearly 90% of world production at the present time. The North American harvest runs from mid-April through early October, with peak harvest in mid-May—August.

Berries signify summer and rightfully so, as the warmer months are the peak harvest for these fruits.  Many berries are suitable to eat raw and most types vary from 50 to 100 calories per serving if eaten raw. Berries are brimming with vitamin C, potassium, and fiber.

Selection

In general, berries should be dry, firm, well shaped, and eaten within a week after purchase. If you can’t eat them that soon, remember that berries freeze well! It’s best to buy berries that are ‘in-season’ as they’ll cost less and are more ripe and flavorful than ‘out-of-season’ berries.

Stay away from containers of berries with juice stains which may be a sign that the berries are crushed and possibly moldy; soft, watery fruit that means the berries are overripe; dehydrated, wrinkled fruit that means the berries have been stored too long.

Select blueberries that are firm, dry, plump, and smooth-skinned. Berries should be deep-purple blue to blue-black; reddish berries aren't ripe but can be used in cooking.


Storage

After purchasing berries, check the fruit and toss out any moldy or deformed berries. Immediately eat the overripe berries within 24 hours. Return the other berries back to the original container or they should be arranged unwashed in a shallow pan lined with paper towels, and washed just prior to use. The berries may be topped with a paper towel to absorb any additional moisture. Plastic wrap the entire container. This will ensure the fruit retains its freshness, but generally berries should be eaten within one week.


Freezing Berries

Because berries have a short shelf life, an alternative to enjoy them year round is to buy them fresh and freeze them yourself. The secret to successful freezing is to use unwashed and completely dry berries before placing them in a single layer on a cookie sheet in the freezer. Once the berries are frozen, transfer them to plastic bags or freezer containers. Frozen berries should last approximately ten months to one year.


Preparation of Berries

When you’re ready to use the berries, go through the lot once more to sort out any undesirable fruit. Then, rinse, drain, and pat dry the fruit. Commercially frozen berries do not need to be ‘cleaned’ or thawed. If you froze your own berries, a quick rinse may be necessary.


Berry Helpful Hints

  • Blueberries tend to change color during cooking. Acids, like lemon juice and vinegar, make the blue in blueberries turn red. In an alkaline environment, such as a batter with too much baking soda, the blueberries may turn greenish-blue.
  • To reduce the amount of color streaking, stir your blueberries (right from your freezer, if frozen) into your cake or muffin batter last.
  • When making pancakes and waffles, add the blueberries as soon as the batter has been poured on the griddle or waffle iron. This will make the pancakes prettier and they'll be easier to flip. If frozen blueberries are used, cooking time may have to be increased to be sure the berries are heated through.  
  • Whole frozen berries destined for your baked goods should be used frozen. Gently fold into pies, cakes and muffins just prior to use.
  • Store whole frozen berries in their unopened or tightly resealed packages in your freezer. If berries are to be served alone, thaw until they are pliable and serve partially frozen. Add sugar to taste — it brings out both the flavor and the luscious juices.
