With blueberries now in season, it’s essential to master the art of keeping these juicy and delicious fruits fresh for adding to scones and muffins. There’s nothing more disheartening than purchasing plump blueberries only to find they’ve gone off within a day.
Blueberries are notorious for quickly succumbing to mould and turning mushy if not stored properly. A little-known tip is that they shouldn’t be kept in plastic and must be removed from their original supermarket packaging straight away. This is because blueberries contain high water content, and plastic containers lead to increased moisture—a perfect breeding ground for bacteria that turn them into a disappointing, mouldy mess.
Food enthusiasts have flocked to the Cheap Meal Ideas Facebook page to share their best techniques for keeping blueberries fresh after one user sought advice.
Charlotte Bray asked: “Any suggestions on how to keep blueberries and strawberries from going bad in just a couple of days?” The majority of responses emphasised that vinegar was the key to prolonging the shelf life of blueberries.
Andy Clark said: “I always wash with water/vinegar and store in plastic containers with paper towels in the fridge. I’ve found my blueberries can last close to four weeks like this.”
Tonya Price said: “Soak for five to 10 minutes in cool water with white vinegar in it. Rinse. Dry on a paper towel-lined cookie sheet [baking tray]. Seal in air air-tight bowl.”
Linda Paxton advised: “Wash and rinse them in vinegar water before putting in the refrigerator. They’ll last longer.”
Sky Hohner shared: “Vinegar bath works amazing. Works especially well with taking that funny feeling on grapes too. I made a fruit salad last time and it lasted nearly two weeks. I couldn’t believe it.”
Kathy White chimed in: “I soak mine in vinegar water for a few seconds, rinse, then clean. They stayed fresh for five weeks. No mould.”
Group members were curious if washing blueberries in vinegar leaves a lingering taste of the acidic liquid.
Stefanie Benson reassured: “No. I do this weekly, and no one has ever complained of a vinegar taste. It just cleans the fruits and vegetables and lessens your chances of getting sick.
“Three cups of water to one cup of vinegar. Or you can do eight cups of water to two tablespoons of vinegar.”
Kathy Burke added: “I just used distilled white vinegar. No, you don’t taste the vinegar. It kills mould spores, that’s why the berries last longer.”
