Experiencing Issues with Freeze-Dried Blueberries: Need Advice!

Hey fellow food enthusiasts,
I recently purchased a pack of freeze-dried blueberries, hoping to enjoy their natural goodness and convenience. However, I've encountered some problems that I can't seem to solve on my own. I'm wondering if any of you have faced similar issues or have suggestions on how to resolve them.
Here are the problems I'm experiencing with freeze-dried blueberries:

1. Clumping Issue: Whenever I open the pack, I notice that the blueberries have clumped together. It becomes quite challenging to separate them, and they don't seem to retain their individual texture. Is there any way to prevent this clumping or to easily break up the clumps?
2. Rehydration Difficulty: I tried rehydrating the freeze-dried blueberries by soaking them in water, but they didn't regain their original texture and juiciness. Instead, they turned out mushy and lacked the vibrant taste I was expecting. Has anyone successfully rehydrated freeze-dried blueberries? If so, what method did you use?
3. Storage Tips: I'm unsure about the best way to store freeze-dried blueberries to maintain their freshness and quality. I've read conflicting information about whether they should be kept in the refrigerator or stored at room temperature. What has worked for you in terms of storage conditions and shelf life?
4. Recommended Brands: If you've had a positive experience with freeze-dried blueberries, could you please recommend some reliable brands that consistently deliver great quality and taste?

I appreciate any insights, suggestions, or tips you can provide to help me overcome these issues and enjoy freeze-dried blueberries to their fullest. Thanks in advance for your help!
