Need to know:
- The best blueberries will feel heavy for their size and be dark blue with a slight whitish, silvery blush. They should deliver a tart but sweet taste.
- Don't wash blueberries until you are ready to use, as the moisture will shorten their shelf life. You can store in an airtight container in the fridge. They also freeze well – place in the freezer in a single layer on a rimmed baking sheet overnight, before transferring into resealable plastic bags.
- Blueberries pair well with more flavours than you may think. While lemon and mint are classically great combinations, consider rosemary, coconut, balsamic and banana. A handful of blueberries on the cheese board is also a guaranteed hit.
- Be aware these little fruits can change colour with cooking and acidity. They often become green or even grey in an alkaline environment – such as bakes that are heavy in baking soda – but turn a more vibrant red when exposed to acids like lemon juice and vinegar.
