Sunday I went blueberry picking with my friend Sandy. I learned from her to pick a lot of blueberries to freeze and then use them in winter. I have been doing this for 3 years now. It is great to have blueberries in the middle of the cold winter. They are locally grown and organic.
Picking blueberries with a friend is fun. We talk and share stories. I put the blueberries in plastic bags (without washing them, and yes, it is one of the cases where you cannot use a cloth bag) and put most of them in the freezer. I use them for smoothies and pancakes. I have not done the Math to see if it is better to do this than to buy blueberries from Argentina in winter or if the best thing is not to eat summer fruits in winter. It will be interesting to see what the carbon footprint of each option is, though, my hunch is that picking them from a farm close to my home has the least impact on the environment.
I love blueberries and they are so rich in nutrients. In New England we do not have many fruits in the cold seasons; the blueberries, thus, provide variety. By the way I only have one refrigerator. I think if you have space in your freezer this is a good idea to save money and have good quality fruits at home.
You may also dehydrate the berries or make a preserve with them. Sandy dehydrates them a little and after that she freezes them. She said that they are great for baking and to make pancakes this way.
To find a blueberry farm near you, try a Google search or ask your friends. Wear long sleeves, pants, and shoes. Bring a bug spray as well. It is always a good idea to wear a cap and put on sunscreen. Children are normally welcome in these farms but ask about their pet policy.
