Spice grinder, coffee grinder, high-speed blender, or mortar & pestle
Fine mesh sieve (optional but helpful)
Materials
Dried hibiscus flowers(whole or broken)
Instructions
1. Dry check:
If your hibiscus petals feel soft or flexible at all, spread them on a baking sheet and dry them in a low oven (around 1705-200°F) for 10-15 minutes until they're completely crisp and brittle.
2. Grind
Use a spice grinder or coffee grinder to blitz the dried petals in small batches. Pulse until you get a fine powder.
If you're using a mortar & pestle, it works - just expect more effort and a slightly coarser result.
3. Sift (optional)
For a smoother, more delicate powder, sift through a fine mesh strainer to remove any larger bits. You can re-grind the coarse leftovers if you like.
4. Store
Keep your hibiscus powder in an airtight jar away from light and heat to preserve its color and tartness.
