Blueberries only ripen on the vine, but unripe ones will still turn blue, making it hard to tell in the store. Since blueberries tend to be expensive, it’s worth the extra trip to the farmers market to taste-test them first.
When are blueberries in season?
They have a shorter season than other summer berries, starting around May and ending in August. On the west coast, you might be able to find berries in April that have been grown in covered areas that increase the heat.
Ripe blueberries are highly perishable, so you are unlikely to find the best ones at a supermarket. Unripe berries have hints of red, however after a few days they will turn blue (but not taste better). This makes the quality hard to determine without a taste-test. Luckily, they grow well in most parts of the US, so you can usually find them at a nearby farmers’ market in summer.
To pick the best blueberries, look for ones that are plump with no wrinkles on the skin (which indicate they are past their prime or going bad). They should be fully blue, however if they have red parts they can ripen a little more after you take them home. If they have white or green parts, they will not continue to ripen.
To store, put them unwashed, in a single layer on a plate or other open container in the fridge. You might pick them up from the farmers market in a paper bag – remove them from the bag as it will trap in the ethylene gas with will ripen them (assuming they are already ripe). Do not store them in a closed plastic container or bag.
They will last a few days to just over a week in the fridge.
Should I buy organic?
The EPA tests show that non-organic blueberries have very little pesticide in them, and are near organic levels. So if you are trying to save money, non-organic blueberries aren’t a high health risk.
The data collected by the EPA looks at the toxicity and amount of each pesticide found in the edible portions of the fruit (not including zest). The full details can be found over on the Consumer Reports website.
Now what should I make?
That’s a good question! I scour the internet to find recipes that use fresh, seasonal ingredients, often with a fun twist. Follow Ask The Food Geek on Pinterest or Facebook to get access to the recipes I find every day.
Each recipe below only uses ingredients that are in season at the same time as blueberries, or ingredients that have a year-round season. Since their season overlaps with the beginning or end of other fruits and vegetables, the recipes are grouped into early season, late season, or anytime they are available.
