Cultivation of blueberries was widespread among the Native American tribes throughout North America. European colonists learned about blueberries thanks to these Native American traditions and brought blueberry species back to Europe. Yet commercial cultivation of blueberries in Europe has been a relatively recent phenomenon limited to the 20th and 21st centuries. Thanks to increasing cultivation in the Southern Hemisphere — including South American countries such as Chile, Argentina, and Uruguay as well South Africa, New Zealand and Australia — fresh blueberries are now enjoyed throughout the year on many of the world's continents.
How to Select and Store
Choose blueberries that are firm and have a lively, uniform hue coloured with a whitish bloom. Shake the container, noticing whether the berries have the tendency to move freely; if they do not, this may indicate that they are soft and damaged or moldy. Avoid berries that appear dull in color or are soft and watery in texture. They should be free from moisture since the presence of water will cause the berries to decay. When purchasing frozen berries, shake the bag gently to ensure that the berries move freely and are not clumped together, which may suggest that they have been thawed and refrozen.
Before storing remove any crushed or moldy berries to prevent the rest from spoiling. Don't wash berries until right before eating as washing will remove the bloom that protects the berries' skins from degradation. Store ripe blueberries in a covered container in the refrigerator where they will keep for up to 3 days. If kept out at room temperature for more than a day, the berries may spoil.
Ripe berries can also be frozen, although this will slightly change their texture and flavour. Before freezing, wash, drain and remove any damaged berries. To better ensure uniform texture upon thawing, spread the berries out on a cookie sheet or baking pan, place in the freezer until frozen, then put the berries in a plastic bag for storage in the freezer.
Tips for Preparing Blueberries
Fresh berries are very fragile and should be washed briefly and carefully and then gently patted dry if they are not organic. Wash berries just prior to use to not prematurely remove the protective bloom that resides on the skin's surface. If you know the source of either wild or organic berries try not to wash them at all.
When using frozen berries in recipes that do not require cooking, thaw well and drain prior to using.
Blueberries retain their maximum amount of nutrients and their maximum taste when they are enjoyed fresh and not prepared in a cooked recipe.
