Crystal Candy Recipe Storage Tips
How to Store Crystal Candy
- Keep your crystal candies in an airtight container at room temperature. Avoid moisture to maintain that iconic crunch.
Can You Freeze Crystal Candy?
- Not recommended. Freezing alters the texture and ruins the glossy shell.
How to Fix Soft Crystal Candy
- If your candy softens due to humidity, leave it in a dry place uncovered. A food dehydrator on low heat can help restore crispness.
Can Crystal Candy Go Bad?
- It can go stale if exposed to moisture. If it becomes sticky or loses its crunch, it’s time to make a fresh batch.
FAQs
What is agar agar?
- It’s a vegan gelatin substitute made from red algae—perfect for crystal candy’s brittle texture.
Can I use gelatin instead?

How long does crystal candy last?
- Up to 2 weeks in an airtight container at room temperature.
Can I add flavors?
- Absolutely! Add fruit extracts, citrus zest, or floral essences like rose or lavender.
