Natasha Gandhi on Instagram: "Don’t buy blueberries if they don’t have that soft white powder on top. Let me explain. That “dust” is called the bloom — it’s a natural shield the berry makes to lock in freshness. No bloom usually means the berries are old or over-handled. I actually flew all the way to Chile and saw the blueberry farms in person. Walking through the fields, watching how carefully they’re picked and packed… I finally understood why Blueberries from Chile taste so unreal in bakes.
