When it comes to telling if blueberries are ripe, there are a few key characteristics to look out for. Firstly, when picking blueberries at the grocery store or farmer's market, you should be looking for plump and firm berries with a deep, vibrant blue hue. These will be the sweetest and ripest! Secondly, give your chosen blueberries a gentle squeeze - they shouldn't feel mushy or soft. If they have brown spots, these can just be picked off as they don't affect flavor. Lastly, you can pick up the carton of berries and lightly shake it; ripe ones won't move around much, while unripe berries will jostle each other in the box. The final test of the ripeness of your chosen berries is by taste testing one or two! Ripe blueberries have an intensely sweet flavor, so if yours don't quite hit that mark, then they probably need another day on the plant before being eaten! Try following these steps next time you're shopping for fresh produce and you'll always know exactly how ready your fruit is for eating.
