To choose the best blueberries at the grocery store, you'll want to do a visual and a smell check, but also keep in mind the season and where they were grown.

Blueberries come in many varieties, so rather than focusing on the shade of blue, look at the actual shape of the blueberries to ensure they're plump and full-looking.

You might also notice a coating on the blueberries that makes them look slightly gray or silver. This is called a bloom, and it's normal.

Fresh, good-quality blueberries don't have much of a smell, but a heavy sour or off odor can indicate they are past their prime. Do a visual check for fuzz and mold.

The best way to guarantee good-quality blueberries is to buy them in season, meaning little time passes between when they are picked and when you add them to your grocery cart.
